It knows it's vulnerable to criticism of its unhinged claims and creepy practices, so it pre-empts those criticisms and gives them a derogatory label. It suggests a person would be hateful or even lawbreaking if they dared to voice even the most valid of concerns.
Yes, absolutely. It's quite a common tactic within genderism, when you think about it. Someone has thought it all through.
And most people are taken off guard by the disproportionate, well prepared response of outrage to reasonable, sensible, predictable questions. It's destabilising and suggests that we don't know what's going on (you don't, because you've just been ambushed), which leads many people to back away and stop asking questions.
Long term as a strategy, though, what I think tends to happen is that although many people will just back away from flashing 'Here be Dragons' warnings, some will find their curiousity piqued. Or even peaked. And start to ask questions.
We all know what happens when you ask questions.
