Depends on what you mean by accountable. If you mean punished for expressing personal opinions, regardless of how insulting said opinions may be to any particular social niche, no. That is the essence of the 1st Amendment.
Slander, libel, and threats that would be actionable under law remain actionable under law in any case.
First Amendment just means the Federal government can't prosecute you for burning your flag or saying the President (any President) is a fucking moron. It doesn't cover illegal comments such as falsely accusing someone of being a traitor or a child molester.
In this case, by accountable, it means they are held responsible for saying it. They can't deny they said it or accuse others of twisting what was clearly a specific statement. Those former Harvard students can't say "I was just joking" or "my dog did it". It's their account and they are responsible for the content.
Or even more bizarrely, once you figure out you stepped in it you can declare the media to be "dishonest" --- for daring to
quote you verbatim,
complete with audio and video (in the bizarre world of self-delusion, once you declare an event to be an unevent that never happened, anyone who doesn't go along with your Memory Hole self-revision in spite of
recorded evidence becomes "dishonest").
---- And then you can flip flop your original faux pas
with "DON'T THEY GET SARCASM?" in a delivery that there's no way to qualify as "sarcasm", a delivery you were offered a way out with an alternative explanation and declined it, doubling down on the literal in no uncertain terms...
---- And
then, once the winds blow the
other way and the "sarcastic" characterization, dishonest though it is, deflates your original hair-on-fire rhetoric with your drones,
you can flip flop on your own flip flop, reverting to the original with
"I was sarcastic but not that sarcastic".
"Oh my remark is bullshit? Well I --- uh ---- it was 'sarcasm'. Yeah that's it --- sarcasm. I don't know what I was babbling about earlier. I was just grabbing at anything. So I'm with you, the remark is bullshit.
"Oh wait --- you guys over here, you
do like that remark? OK well uh.... I was um 'sarcastic' but not that sarcastic. So I'm with you too. I agree with everybody on both sides."
Having it both ways -- Priceless. Having it one way, then turning it the other way, then turning back to the first way again ---- mental illness, psychosis, disconnection from reality, self-delusion.
Orwell described "Doublethink". Rump has taken it to "Triplethink". Obviously, there's no end in that game.
