This is a straw man argument. You are voting democrat even though they are corporate backed and paid for. So that means you don’t care about workers and are a capitalist corporate shill, right?
Just like you have a reason to vote democrat even if they do things you don’t agree with, others have the same rights to vote for parties even if they don’t align with all the policies of the party.
Stop debating anywhere and everywhere trying to convert people to your cost. There is a time and place for everything. Guerilla debating does more harm than good. Example: this post.
