Politics is rarely discussed here to begin with and something like 65*% of LWers are liberals/socialists.

Yes, but people on the far right are disproportionately active in political discussions here, probably because it is one of the very few internet venues where they can air their views to a diverse and intelligent readership without being immediately shouted down as evil. If you actually measured political comments, I suspect you'd find that the explicitly liberal/social ones represent much less than 65%.
