I don't have much to respond to because I appreciate what you've said and even agree for the most part, however:

Voting Democrat is always in your interests.

The Democratic party is not some force of good, and their administrations and policies still harm the working class and other marginalized groups. They just manage to do less harm and placate us slightly more than their primary opponents.

Voting democrat is more in my interest than voting Republican, but not as much as having an ancom in office. It is not in my interest in general, as I will still be shooting myself in the foot because it's better than having someone else shove electrodes into my brain.

You may say that it's the effect of "corrupt dems," but that's a myopic understanding of the party and its motives. It is an ideologically driven party, it's just that that ideology is an uncomfortable truth: liberal capitalism. In service of that, it allows the input of marginalized groups, but will never allow us to gain full autonomy and control over our own lives as that would not serve capital.

I refuse to buy this narrative that any progress be made has to be made under the banner of a particular party/organization/group.
