I don't think they care what N is, they are just scapegoating a vile group they know will have no defenders, and they can use it to silence the critics by associating them with that group.

Bingo.

Today its the pedophiles and 15-17-philes (those are this fake group adolescent, which are also tried as adults when convenient).

Tomorrow, its the adult sex workers.

Then its the fringe group's topics that is on the outs with the majority.

Then they come for you, and nobody is able to speak up because they banned protests.

... To paraphrase Martin Niemoller.
