But I do notice you on every trump post insisting people are screaming both sides
Another common tactic/fallacy is exaggerating the claim. Example: saying something “screams” about “both sides”. The bit about screaming is unneeded and is just added to make it easy to argue against it.
and others taking legitimate criticism of biden as people screaming both sides
That’s not the same and not what is meant as “both sides”. And again, people aren’t screaming. I’d maybe take your comment more seriously if it didn’t ignore things while adding a fallacy to discuss a common fallacy.
