Gender roles, if they are not enforced by qt, then why are poster children like Jazz Jennings, who was diagnosed as a child based on his gender nonconformity still held up as ideals of early transition?

I don't think Jazz was diagnosed based solely on gender non-conformity. I think she stated outright many times she was a girl, and gender roles are deeply ingrained in society, so she probably wanted to be treated the same was society treats other girls because she's a girl.

I’m not gonna address the claim that “cis” people enforce gender more because one kindergarten teacher 21 years ago said blue is a boys colour other than to laugh at how bad that argument is.

In my personal experience, trans people are more likely to challenge traditional gender roles than cis people.

Do you think the marketing teams at hallmark are gender critical and they choose pink for Mother’s Day because of that? Or because it’s already heavily associated as a woman’s colour and mothers are women?

Yes pink is heavily associated with women, but I think cis people decided this.

In what way does it challenge gender norms when a thousand men say they are women because skirt goes spinny, because they are submissive, because they enjoy beauty culture, or because they enjoy participating in activities societally deemed feminine?

That's not the reason MTF people transition.

Wouldn’t a challenge to gender norms be a man donning a skirt and taking up soap making because he likes it and acknowledging that he is still a man?

Do you believe the stereotype that trans women are hyper feminine? One of my friends is a trans woman and doesn't wear dresses and skirts. She wears the same clothes she wore pre-transition.

How can straight and homosexual mean multiple conflicting things and still be effective communication? How is language meant to work if words do not have concrete meanings?

Being attracted to trans people who share the gender identity you're attracted to doesn't necessarily make you bisexual. I'm attracted to cis men and passing trans men. I had a few people on this sub insist I'm bisexual because I'm attracted to cis and trans men even though I'm straight.

I have nothing against the LGB community. Gay marriage was legalized in my state when I was finishing 9th grade, and I excitedly told my classmates in US history class the good news. The beginning of that year, the teacher had us write an essay about any government policy, IIRC. I remember I wrote about the military's "don't ask, don't tell" policy. In later years, a bisexual girl asked me out. I declined because I am straight. She is currently in a relationship with another woman, according to FB. I called out homophobia numerous times in my life.

But I'm straight. People define their sexuality differently. For some "gay" means they are attracted to cis men and trans women who don't fully pass as female. For others, it means they are attracted to anyone who has a penis. For some other people, it means they are attracted to cis and passing trans men. People should be allowed to use the terms whatever they feel best describes their sexuality.
