this is...very alien to me. i'm 100% certain there are plenty of facebook engineers who are comfortable wearing Facebook branded clothes at this time. i know some.
I will say that in my current area that's obscenely republican after January 6th I actually started hiding my employment from the general public. After Trump got banned from Twitter and Facebook some groups were making lists of known Facebook and Twitter employees and there were generic threats of violence. The local BLM group that put up some billboards and signs eventually gave up removing graffiti because it would just get vandalized again right afterwards. One of the vandals even got caught in the act and local police refused to even warn the guy.
Didn't FB leadership consider the welfare of employees before banning Trump? They should've known violence was an inevitable outcome.
Stay safe dude.
It's easy to do that when you work from home and never leave the basement
