Because a bloated propagandist helped a joke of a candidate win an election against the one opponent said joke could beat in a general election does not make said propagandist a 'genius'. Motivating the masses via hate is a political tactic as old as time.
The "left" has become accustomed to "people blindly agreeing with them" because, yes, the majority of humans agree that being judged based upon the actions of outliers in one's ethnic grouping isn't fair and because, yes, quite simply, capitalism is easier for those who have access to capital, and those who don't have access (to capital) are *very* self-aware whereas those who do often aren't self-aware.
Also, calling racists "racist" still works every single time. It's not an ideological battle. It's sheltered stupidity vs. wide-eyed awareness. At a personal level, everyone knows that racist thoughts are wrong--again, because no one likes being judged on the basis of others' actions. It only becomes comfortable when groupthink takes over and people start to feel good about blaming broad demographics for their lot in life.
I feel like most of you guys who are still here defending this ridiculous notion of a political party are doing so because of your religion, mostly.
