WOOOOOW that choice of words. Wanna rethink that one buddy before bringing degeneracy into the mix ?
First off, let's not forget that a lot of socialists and harder leftists in general today are trans/LGBT activists who feel abandonned both by the system and by mainstream liberal who either see them as useful fuel for the elections or at worst, a slight embarassement. Let's not forget the number of time democrats won almost only through POC votes, only to be thoroughly thanked and subsequently ignored. It took doug fucking jones winning in alabama and a LOT of noise from black communities to get a black chief of staff, the ONLY black chief of staff. The ONLY member of the democrat caucus to have a black chief of staff.
The reason a lot of socialists and leftists don't like centrists is that they're really good at paying lip service but then get really frisky when it gets about talk for unions ("Oh i'm all for unions, just not this one"), actual healthcare (or "promising ponies"), an actual stop and condemnation of police brutality and a stop to the rampant aggressive capitalist system that has bloated america and is influencing education, poverty, ecology and such.
Not that I support Manning (I don't, I find she lacks policies and I don't like her style as a candidate), but I can fully understand why people would love a "fuck the police" approach when said institution seem beyond repercussion and is more or less populated more than half by criminals at this point
