I think it's a good idea. Why not fight with the same weapons? If people ask for new gender constantly we should be allowed to do the same. I have no problem with the LGBTQ community, there only problem I have is that people want to be something specials. Everybody should be allowed to have his own beliefs. And if someone only beliefs in male and female, why call him transphobic? Just let everybody live in peace without violence.
try that in the workplace
boss: "good morning ladies and gentlemen"
jeff: "boss dont call me a gentleman. im an aggressive trans using pronouns 'them'"
boss: "well dont call me boss either. call me 'the person that pays your wage if you get on with your work'"
jeff: "dont tell me what to do.. im not a slave"
boss: "well 'them' is not listed on my payroll so your right. so as a free person you can go home and find another job"
