That's not what he said. He said incels are republicans and he's right. Those people identify with the hatred and misogynism that comes from the toxic far right.
"Incel communities have increasingly become more extremist and focused on violence in recent years. This has been attributed to various factors, including influence from overlapping online hate groups and the rise of the alt-right and white supremacist groups."
Please read carefully the segment I was responding to. He was talking about the right wing, not the "incels". For that matter, I don't even know what an "incel" is.
In your quote, I do not see the word "Republicans" anywhere.
