I think there's something to be said for saying that posters are FFs even if you disagree with them politically. There are definitely posters on this forum who are good people, and state their case in a reasonable manner. The fact that I disagree with many of their views doesn't make them a bad person, in my eyes. On the flip side, there are also posters who I agree with a fair amount of the time, but who are enormous tools. IMO, the FF/HP rating should be at least mostly independent of whether or not you agree with their views. I'd hate to think some people think of me as a horrible person just because my views are different from theirs.
But don't things like obvious white nationalist sympathies and North Korea apologism go far beyond simply "different views"?
Yeah, there are limits, though I think in the case of someone like Santander, he's just trolling/become a parody of himself.
