I'm not assuming anything.
The right is attacking the left to try to reduce voter turnout. They do this by criticizing Democrats for "not being left enough" even though they are the most viable leftish option and the Republicans are worse at that exact thing. They're doing this all over the world right now but just in the US. We HAVE to stop this attack.
When you criticize the left for not being left enough without adding nuance or adding that the right is much worse on that topic, you're either purposefully or accidentally participating in the attack whether you like it or not.
No criticism, just facts.
