Itzik,
I’m not sure they are trolls, as much as they are genuinely krum. They literally live, breath, and bought hook line and sinker into the egalitarian American secular culture with all its excesses and immoralities. And then they actually try to make their egalitarianism and secularism and immoralism into the new age Torah no less! And even worse propogate it and attempt to annihilate any true rendition of the Torah.
Literally on this very site you have more than a handful of such unashamed posters. I venture to say that in online forums they outnumber Torah True individuals. (Probably as a result of many Torah True Yidden eschewing usage of the internet.)
