He didn’t provide an example, unless you think trolling journalists is a “gem”. His other claim is unfounded.
There should be a "BS Law" were someone claims to have evidence, then refuses to present it no matter how pressed.
He claimed they had a math proof, as we see from the other comments, that wasn't /pol.
He claimed they trolled journalists. Whatever.
He claimed they had something to do with convicting a sex criminal, then provided zero evidence to back that claim up.
In no way is any of this justification for the racism that is the central message of /pol.
