Using an alt for obvious reasons.

I am technically agender (though mostly just autistic) and have a relatively weak preference for they/them pronouns. I also have a much stronger preference for not discussing gender issues at work, especially as the field/country I work in skews seriously conservative. Being "this weird guy with pronouns" would be highly unenjoyable and costly.

Considering those factors I am perfectly fine with presenting masculine, letting people assume I am a man and use he/him pronouns.

A mandatory place for them forces me to either put they/them which would have the consequences mentioned above or he/him which feels somewhat unpleasant.

I have talked to other people in a similar situation.

The goal seems to be to avoid their presence revealing somebody is not cis, but with a low overall percentage of trans people in the population it is enough if ~10% of cis people provide them for it to not be such an indicator, which can easily be achieved.

I will reward best arguments as to why they should be required, either directly or socially, in a couple of weeks probably.
