Congrats to the DSA for winning the mayoral seat in New York City! The primary advantage of this is that it advertises the DSA as an organization that, at least nominally, supports socialism. Mamdani's position, however, helps highlight the futility of trying to change capitalism into socialism brick by brick from within, why electoralism is inevitably a dead-end, and the only utility it has with respect to socialism is advertising.
You are correct to say that many places do not have a DSA, or a PSL. This is why the focus should be on grassroots organizing, not electoral campaigns. Imagine if the resources used by the DSA to canvass for elections were employed by disciplined cadre sent out to these areas to start new chapters! The PSL does this, but by nature of being a demcent party is smaller. The strength of the DSA is in numbers, the weakness is in always tailing behind when it comes to strategy and tactics.
To the DSA's credit, internally there is widespread debate about reform vs revolution. If the DSA successfully converts to a revolutionary organization, then I will re-evaluate them.
I am not "ranting about people wanting the general public to vote as left as possible." This, again, is a dishonest characterization of myself and the Marxist position on resource allocation in an organizational capacity. I am vocally opposing making elections the primary capacity by which an organization uses its resources and efforts, and instead advocating for making grassroots organizing the primary effort. This is the Marxist position, not what you have been presenting in memes and comments.
