They've already proven that they won't allow people back on their side.If anything, it should elucidate the futility of calling out liberal hypocrisy. They don't care. Hypocrisy is not a sin to them.
As much as they punish people for insufficient orthodoxy, they're more than willing to throw those concerns to the wind if it means they'll gain more power.
Then again, it's not like we're trying to convert them to begin with. They're already dyed in the wool. If anything, hypocrisy call-outs are meant to woo any fence-sitters remaining.
I bring this up a lot because it's funny. Remember when "alt-right hate bigot" Joe Rogan endorsed Bernie Sanders? Instead of celebrating how big a win this was for progressives that this huge influencer switched to their side, AOC literally retracted HER OWN endorsement of Bernie saying that she couldn't do it if Rogan did it.
There is no path to unity or forgiveness for these people.
