We don't have to talk in hypothetical. The democratic party ran on a campaign of kicking immigrants out of the country, continuation of the declining state of late stage capitalism, and state sponsored slaughter of Palestinian children overseas.
They could have not done that. Its as simple as that. Straight forward. They could have run a campaign standing up for human rights and a platform of workers rights. Thats it. Thats the problem. The problem is a far right conservative party vs a fascist party and those are the only 2 parties. Democrats lost the election. If they had campaigned differently, they wouldn't have lost. Demand better from politicians, not for people to vote for the murder of their own families.
Its working, horrifyingly. In several communities lately ive seen moderators start to treat violent racism and antisemitism as personal beliefs that do not on their own necessitate banning. This in private progressive leaning communities too. Eugencist christian white nationalism is becoming a normal tolerated ideology to have.
Instagram is especially bad too. I see a lot of people talking about Twitter, but not enough about Instagram.
