There is zero real world evidence of trans people being any more likely to be sexual predators, so the example you gave would be a bigoted statement predicated on a lie

First: I'm not going to be linking to any evidence of this (equally bigoted) statement because I don't want anyone here to be confused about the intent of the comparison. But it should go without saying that there are absolutely examples of trans individuals committing sexual assaults - just like how any other random sampling of people large enough will contain examples of any number of hideous crimes committed by those people.

Second: The point isn't that there are people who commit those crimes within that group, the problem comes from attributing those people to a quality or belief shared by an entire minority (in the western world) of people whose membership in that group makes them subject to violence, bigotry, and marginalization themselves.

It isn't criticism, it's islamophobia, and has been used as the justification for all kinds of unspeakable violence committed against Muslims all across the world.
