These folks aren’t operating in good faith.
Have you ever, and I mean ever, seen them point at a deeply divided congress under Biden’s tenure as President? Have they reckoned with the fact that anything Biden does by executive order can just as easily be undone? Do they talk of how America is largely moderate and not at all far left? Look around and see them continue to deny Bernie’s loss of nine years ago, even while they blame Hillary ad nauseam (twice today by my reading.)
There’s little if any good faith coming from these folks, and so they take the cheap, uninformed hits and block their detractors. They know nothing of compromise and little of how governance works, and often can easily be confused for Trump’s own lifeblood.
