For me it's been like a splash of cold water to the face, remembering just how fucked up 
tier liberal takes were, are, and will likely continue to be.
I'm sure there's downsides to complacency, but it was nice having some ground assumptions when going into a thread, like "society can and should be improved somewhat" or "the ruling class acts in its own immediate self interests and any other claims regarding their motivations are propagandized lies" or "climate change is real, it's bad, and it's getting worse," or more trivial stuff like "Tesla cars aren't good."
I'm sure potential comrades are out there and while it really is necessary to reach out to more people at some point (offline too, orgs especially, but while we're here, you know?), it's been sobering to realize just how far rightward mainstream "progressive" liberal thought really is on average. 
I'm still naive, I still think the coherent arguments are good and the tactical PPB is just okay. Of course, it's like <1ppm of liberals who can get over the "PROPAGANDA! THAT'S A CCP TALKING POINT" instinct and start to do even basic Chomsky-level analysis of the world. "Thought-terminating" is absolutely apt to describe the way these people operate.
Still, I don't think I'll transition to just sending giant lenin emojis to guys as rebuttals. I also don't really blame anyone who wants to. At any rate it is literally just posting words on the internet, it doesn't matter either way.
I want hexbear to get more new and old comrades on board. Libs somehow continue to surprise me with how monstrous, how proudly ignorant they are. Same stuff as always, really
