Suppressed by the people in power. It's better for them if we fight over culture war bullshit and that's (IMO) why the right pushes so hard against things being "woke" or "dei" or whatever new scary buzzword those dumb fucks come up with.
We're too busy arguing amongst ourselves to realise we should all be looking up at the corrupt rich. But with bought off media and the ability to push propaganda at a previously impossible level just a few decades ago, a ton of the population is kept perpetually angry because non-white/straight people have the audacity to exist.
I'm a native (aka native American/indigenous however you want to call it) and over the last few years I've noticed people are increasingly comfortable showing their racism. I get followed around in stores while I'm shopping for groceries occasionally, I get managers staring me down because I took too long looking around and they think I was trying to steal and that my debit card will be declined, people happily making small talk with others and then blankly staring at me and saying nothing to me even when I'm being pleasant to them etc. All anecdotal of course and I could just be getting more bitter as I get older, but it honestly feels like a trend to me.
I've been dealing with that shit since I was a teen, you always get judged just for having the audacity to be born the wrong skin color anywhere but it's (anecdotally) gotten much worse over the last few years, which just so happens to coincide with the rise of the right all over the world.
I've learned to live with it, and while it pisses me off in the moment I've learned to let it go after it happens. No sense staying angry over losers, best to prove them wrong and then forget about them.
2016 was the year that people demanded a populist leader. The DNC sabotaged Bernie, which lead to low D voter turnout and the RNC bent at the knee at Trump's threats to run as a third party.
How did the DNC sabotage Bernie? Bernie was allowed in the Primary despite not even belonging to the party, and primary voters chose Hillary Clinton by a huge margin.
How can the DNC possibly suppress them? If anything, the fact that they let Third Party Bernie Sanders run in primaries for a spot on DNC presidential ticket, multiple times, is astonishing.
And rightly so. AOC supported the bill which conflates any criticism of the state of Israel as anti semitisim. Friends tell friends when they are wrong.
