Part #2, By in-between I meant biologically intersex people, it seems like you aren't aware that it's a thing. These people are born with both sex organs, usually some not being properly developed, and it's impossible to tell what they will actually identify with later in life. That's why Germany just introduced the third gender option on birth certificates - you legitimately can't tell by their genitals if they're male or female.

Also you say you don't hate trans people, but then why use the slur to describe them? It's like saying "I don't hate black people" and then immediately raise the n word for them. Even when you come from the mind of "it's just a word", do you really need to use it? I mean I used the argument for a different word until I realised I never fucking use it anyway so why is it even worth the debate.

wizzwizz actually explained the issue very well already. Your experience with transgender folk does not speak for every trans person either. But it's true that we should find a way to differentiate between the two. Brain scans may be a possibility, as they have a different structure than that of a non transgender person.

Additionally, you need counter statistics to your suicide statistics to see the full effect of transitioning. By that I mean suicide statistics before and after transitioning, as well as the effect of conversion therapy. You will find that transitioning reduces suicide, and that conversion therapy increases the suicide risk greatly. Transitioning is currently the best possible treatment available, and it actually includes therapy that starts before they can transition, to make sure they actually want it and that it isn't trauma and non-sex related identity issues. Also, if they are accepted to be just like any other member of society including being called by the gender and name they changed to instead of getting outcasted or bullied, they are less likely to commit suicide.

There is a very small percentage of people that regret transitioning, some have even detransitioned, and they are often shamed by anyone for making the mistake without anyone acknowledging their reasons. These people have usually been forced into gender roles and started feeling wrong because they arent a perfect stereotype. I remember the case of a girl who transitioned and only after going through with breast amputation she got traumatised and realised she made a mistake. Her father would always force her to be a stay at home woman, always supposed to wear dresses, cook for the men, but she hated it and felt wrong because she was more of a tomboy. She never realised that its completely fine to be a tomboy and it made her think she should be a guy. And I sympathise as all the girls back in my school days were very stereotypical while I was more of a tomboy as well, and felt out of place due to it. That's why it's important to not force gender roles and let children and young adults be able to express themselves freely. The most afraid of their kids turning out to be transgender or homosexual and reacting by forcing stereotypes and gender roles on their kids are doing the exact opposite to help it. If your boy wants to paint his nails, wear a dress or play with dolls just let him. If your girl prefers dinosaurs and cars and pants over skirts and dresses then let her. Kids love to try things out and experiment, it's good to let them explore what they like and what they don't. Plus, they're kids, they play and have fun and don't concern themselves with societies roles yet. Freeing people of thinking that they need specific personality or visual traits to be part of a gender would greatly reduce the risk of wrongly transitioning people.
