It's an indictment of their characters only if you think being a white reactionary conservative (at least on race issues) is an indictment of one's moral character.
Right, the problem, in my opinion, is that Jado isn't quoting these posters to merely point out that they're "white reactionary conservatives," he's quoting them to imply that they're racist, not level-headed people, and eager to defend evil people. I think that's an unfounded conclusion based on these posts, numerous though they may be.
I'm not a white reactionary conservative and I find myself understanding where a lot of these posts are coming from, so unless either of them have explicitly stated their political beliefs (which I very well could've missed, if so, sorry), that might be jumping to conclusions too.
Regardless, being white, reactionary, and a conservative per se aren't signs of weaker moral character, in my opinion. I realize many would argue otherwise and I don't know if I'm ok with that.
