in regards to misplaced frustration and angst, pretty much, tech is mostly filled with frustrated, unattractive (physical and personality wise) middle aged men, who believe that the only way to find a mate is to swallow this liberal agenda so as to make themselves appear as more of a 'nice guy', and thus in their twisted little heads, becoming more attractive to members of the opposite sex. Typical beta mentality.

edit: actually, I should say that tech is not actually like this, its mainly the illusion that reddit and HN present.
