I'm sure many of them are bots (as has been documented and proven on other platforms) but I assume they're mixed in with the actual people that happen to agree with the bots or get swayed by the bots' takes.

Don't underestimate the stupidity of the average flesh-and-blood American. (And before anyone says it, yes, I know there is stupidity elsewhere, but I happen to be an American, so I don't feel bad about criticizing them).

I try not to get into the habit of assuming that every braindead comment or post comes from a bot (though they may be indistinguishable). I am very aware of the bot/paid trolls issue, but I also assume there's the possibility of at least a non-zero share of the firehose of Internet stupidity which is generated by the sausage-like appendages of someone who is very much alive that I am forced to share a country with, and that they may typing those things in earnest without irony.
