Copying my comment from another thread: when I need to discuss "change through bourgeois electoralism" with libs I love sharing this interview:
It's so perfect; it's a reputable Western newspaper so you can share it in almost any setting, just preface it for plausible deniability with something like: "It's a hilarious read, one of the greatest modern liberal intellectuals debates a genocidal maniac frothing at the mouth!"
Libs love the idea and usually swallow the bait expecting funzies, they looooove them a stuck-up Brit "speaking truth to power" and handing out "hitchslaps".
And then Stalin absolutely demolishes Wells and it really fucks with their world. Wells says FDR's New Deal will bring about socialism in the USA and Stalin's like nah cause the economy is in the hands of capitalists so at most you will get some concessions which capitalists will keep fighting to revert. Stalin's arguments are so clear and concise, and his predictions are so plainly correct, while Wells is just being confidently wrong and terribly smug about it.
I had some success with it too, including one well-meaning lib literally telling me the next day, "Stalin was right" which are the three words I would not expect a lib utter under any circumstances.
