As long as they don't talk too much about what 'new' gender they are, I don't really mind trans.
However if they get triggered over a mispronunciation, then they have to shut the forget up, it's like their gender is the most important, the most complicated thing in life to them during that very moment.
And lets not all forget that there are only two sperm cells, male and female. Just because you call yourself a transgender male doesn't mean you're a female, it means you're still a male that's just attempting to morph into a female body. Well guess what bud? That's not how it works in real life. In real life, you stick to one gender, the gender you are given, and that's it. There will never be a new gender for a good century at the very least, yet all you transgender people out there think 'oh so my gender doesn't exist? I'll have you know it's 'insert gender here' and you better add it on there!' and as a result, in big communities like tumblr, there are apparently as much as 63 genders. That's just loving ridiculous.
TL;DR: Don't really mind them if they act normal, through if they bring up genders too often, I'll get ticked off.
