That requires a level of self awareness that these people simply do not have.
No, I think
@Arachnomatricide might be right here. No one is more inclined towards intra-community witch-hunts than SJWs on Twitter/Tumblr. The vocal minority may be vehementy against any restraint when it comes to "protecting" trans people, but most people, even SJWs, have a threshold for this sort of stuff. For instance, the infighting between transmedicalists and transtrenders is evidence that there are SJWs who are able to draw the line.
Tumblr was my main platform for many years, and I am pretty confident that SJW-ism has already peaked and is on the decline. There was a point about four or five years ago where shit was really out of control and people truly had zero self-awareness. Now, most of that crowd, while they still belong to the same overall school of thought, have become more critical, likely as a result of growing up.
People being afraid to speak up for fear of backlash from their own communities is a very real thing. It is common for SJWs to equate "seldom" to "never" to silence and invalidate people who bring up their fear of transgender rights being abused. Yes, guys like Yaniv are not very common in the greater scheme of these things, but that doesn't make it a non-issue; there still need to be systems in place to prevent perverts from exploiting a well-meaning system.
Personally, I think that you have to be required to either legally change your name or at least partially transition before filing these sorts of "discrimination" suits, and that services pertaining to the handling of genitalia (like waxing, piercing, etc) should automatically be exempt.
