These people are neoliberals masquerading as leftists because they have a slightly more progressive stance on trans issues lmao
Guys pleaseee vote for the blue genocide master because he's doing one less genocide than the other guy! There's no other option, stay in the 2 party system!!! I also will argue against any revolutionary work you do because that's not going to get anything done don't be silly votes blue expecting a change
This argument would be perfectly coherent if there were a sincere effort to court leftist votes. There isn’t (ever) so the argument is moot. The response should be a simple “don’t expect votes you didn’t campaign for.” Honestly, it would be trivial for the Democrats to win every election at every level of government forever by promising like 1% of the popular and useful things that people want and then doing them. But they won’t, so again, moot.
In fact, performatively shitting on leftists is a longstanding Democratic tactic https://en.wiktionary.org/wiki/hippie_punching
Also, Democrats would always prefer to find an excuse to lose rather than a way to win, so blaming leftists serves multiple purposes.
