Not all of them are like that, at least not me or some others I know. Some just like to get political like feminists.
I can recognize myself as a dude and won't bother if someone calls me a "he", pronouns are just silly stuff. Sex, gender, sexual identity, all can have relatioships with each other but doesn't define what they should be.
People need to understand you first and judge later if there's a real reason to change pronouns. Language as genders are a social construction that changes over time if it is needed, no need to push stuff into people's mouth.
And let's be honest, it seems like on the future there will be trans people everywhere. What's even the real value on genders if half the girls have a cock and "pussy_destroyerXXX" is a bearded guy that used to have vagina playing COD from his basement?
