drag artists ... complained... the network was forcing them to ditch their stage names
Um, I skipped over this in the subsequent "FB is evil" stories, but is the central premise actually true in the first place? FB may be (trying to) force people to use their real names for their personal profile, but it already has mechanisms in place for "public persons", businesses, etc to have a page/profile. Your personal profile is for you to network to your friends, these other pages are for you to interact with fans, promote your business/product/band/whatever.
It also means an actor can use their real name for their private profile and their actor name as their "public figure" page which is one example of supposed hypocrisy that was levelled at FB. Similarly a politician can have two profiles. This is all within the existing rules of FB so did I miss something in the story or has it been glossed over in the interests of a good ruckus?
This does not address the issue of transgender individuals who may endanger themselves but the story doesn't seem to be about them.
