Study where they found the most common comorbidities with gender dysphoria are major depressive disorder, adjustment disorder, and phobias:

Study where elevated rates of autistic symptoms and lack of empathy were seen in patients with gender dysphoria:

https://pubmed.ncbi.nlm.nih.gov/32770077/

This next one is interesting because while it concludes that patients with GID don't have other psychiatric comorbidities, the paragraph above that states that GID patients had instances of suicidal ideation at around 70% and rates of self harm at around 30%. People don't hurt themselves or want to kill themselves for no reason, so I find it odd that they found this, yet miraculously found such low rates of other mental illnesses. You could argue that it's the dysphoria causing the suicidal ideation, but again, most people who end up in that mindset didn't get there because of one specific thing. It's usually a combination of factors, and typically more than one mental illness. This study is a decade old though, the previous 2 are more recent:

This is an article which has many other studies cited at the bottom but the article itself discusses how people with GID are up to six times more likely to be autistic:

Regarding Blaire and Kalvin, here is a video where Kalvin and another trans YouTuber discuss an experience where they 'talk to a transphobe'.

https://youtu.be/zGXcvZtKXIQ

You can see Kalvin and London mention that they believe in order to be trans you need to be male or female brained in a body that doesn't match. The 'transphobe' they're talking about compares being trans to being schizophrenic (around 16 mins), and both Kalvin and London shoot this down by saying that they aren't delusional since they don't look in the mirror and see an opposite sexed person. However, about a minute before that (around 14:40) Kalvin says "I know in my brain that I'm a man." Sounds pretty delusional to me.

This next one is only one example of Blaire's where the subject of needing dysphoria to be trans comes up, but Blaire talks about it in many videos. Blaire says that dysphoria is a condition where you're unhappy with your gender role and secondary sex characteristics:

Here is a reaction video (couldn't find the original) but here Kalvin and Blaire both agree that there are 'criteria' that need to be met in order for a person to be trans. It's at 4 minutes:

https://youtu.be/5k04xXGFOjc

Now, if we actually look at the DSM-5 criteria, particularly the section on diagnosing children, it says:

In boys (assigned gender), a strong preference for cross-dressing or simulating female attire; or in girls (assigned gender), a strong preference for wearing only typical masculine clothing and a strong resistance to the wearing of typical feminine clothing

A strong preference for cross-gender roles in make-believe play or fantasy play

A strong preference for the toys, games or activities stereotypically used or engaged in by the other gender

A strong preference for playmates of the other gender

In boys (assigned gender), a strong rejection of typically masculine toys, games, and activities and a strong avoidance of rough-and-tumble play; or in girls (assigned gender), a strong rejection of typically feminine toys, games, and activities

This is what Kalvin and Blaire believe. They think that gender nonconformity isn't a thing and that if you check these boxes that means you're automatically trans. I can't get behind that. This is why I call truscums regressive and sexist.

Another truscum, Jamie Dodger, and a prime example of FTMs who refuse to acknowledge internalized misogyny as a possible motive for transitioning:

https://youtu.be/6Avcp-e4bOs

It's at around 39 minutes, but Jamie poses the question "if transmen are trying to escape womanhood, why do transwomen exist? Why would someone who has male privilege choose to give that up?" Oh, I dunno Jamie maybe because being a man isn't all sunshine and rainbows either but you didn't grow up as a boy or live a significant portion of your adulthood as a man so you wouldn't know that.

Jamie's girlfriend adds fuel to the dumpster fire by saying that transphobia is worse than homophobia (yikes), and attempts to use transbians as a 'gotcha' because "why would someone go from male privilege and straight privilege to experiencing both homophobia and transphobia?" Either they aren't aware that AGP is a thing or they're ignoring it on purpose. They use this to prove their point that being trans isn't a choice. Jamie says "being trans isn't something I strategically chose" while completely ignoring that we make choices based on subconscious influences we aren't aware of all the time. Jamie claims to have known she was a transman before knowing trans people existed. So, what would we have called that before Jamie discovered trans people? We'd have said Jamie hated being a girl, and likely hated being a lesbian. We have words for that, internalized misogyny and homophobia. Jamie would likely claim that because trying to accept herself as a woman and a lesbian didn't work, that makes her a man. However, given that most therapists treating GID do not probe far enough to get to the root of the disorder, and only ask surface level questions in order to get the ball rolling on HRT, the more likely reality is that Jamie didn't get the proper help she needed. Same with Kalvin and Blaire.

I cannot call these people reasonable or sane. I don't care that we might agree that the loudest TRAs are making the whole community look bad. They're hypocrites who claim to have science on their side while ignoring the mountain of evidence that disproves their claims. They throw all nuance out the window because they know most people don't want to think too hard and won't bother taking apart their beliefs and expose them. Truscums pretend to be the authority on all things trans because they 'seem' level headed until you peel back the layers.
