Idk, if your political project is that fragile, maybe it isn't particularly good. This is trying to do the ur fascism thing of painting the opposition as simultaneously too strong and too weak thing, except in a single tweet, so it just comes off stupid.
Contrapoints had a video where she identified a tendency among a certain set of trans YouTubers to spend way too much time and energy calling out "bad" trans people, because they get it into their heads that a) they're the reason transphobia exists, and b) by attacking them, they can position themself as "one of the good ones" and be accepted.
Replace trans with leftism and you get this tweet. "There's no systematic opposition to leftist ideas, the only reason we can't have nice things is because bad leftists give good leftists like me a bad name!"
