That's a pretty slanted recollection of events, I think.
With few exceptions (I don't know this to be sure but I'd be surprised if Breitbarts reaction wasn't LOLFUCKACOSTA), Fox, Dailywire, Nat Review, they all condemned Acosta getting his press pass revoked.
I don't think you can complain about the current President's behaviour towards "members of the free press" when your guy set the precedent. The Doocy incident was a hot mic, not just an overinflated ego throwing a tantrum - and unlike Trump, Biden has also apologised to Doocy (and Collins). I'm not defending Biden per se, but I don't think you really have any scope for holding his feet to the fire given how much, and how much worse, you allowed for with Trump. One is not an iconoclastic firebrand bringing a breath of fresh air to politics and the other a disrespectful POS for doing similar things.
This isn't even a defense of Trump as much as its just laying out the basics. One has the mainstream media running cover for him like they're his personal praetorian guard, the other was maligned as the next Hitler.
The way both have been covered and the treatment they've received is not the same.
FWIW, I have no problem with the demented old bat currently occupying the white house saying whatever he wants to the press, they can all eat excrement as far as I'm concerned, it's just interesting the difference in presentation.
