When I say 'false equivalence' in this context I don't mean 'nationalist protesters are all bad and trans rights protesters are all good'. Of course there are bad actors in the trans rights camp, people who are blinded by their own flag; likewise I'm sure there are well-intentioned and peaceful nationalists who are simply misinformed. I submit to you however that the number of, and danger presented by bad actors in the former camp is severely limited compared to the bad actors in the camp of people who hate foreigners and wish to see them expelled and/or commit violence against them. Even without comparing actual events, that would seem to be self-evident given the trans rights cause itself is centered around support and love for a group of people, and once you do compare actual events the difference is obvious. I've been in the presence of a nationalist rally once, and even as a cis white guy it was a scary thing. I would have absolutely no qualms whatsoever showing up to a trans rights march.
Do you really think the two are basically morally equivalent? That someone could not reasonably criticise rising and widespread nationalist hatred if they don't also, with the same vigour, also call out a handful of zealots aggressively pushing for acceptance and fair treatment?
As I said I totally accept I may have misunderstood you and/or the other commenters here, so please enlighten me if so.
