I do have a problem with those who hide behind that label because they think it provides them a sense of moral superiority to those whom they disagree with
This is an unfortunate fallacy.
Nobody describes themselves as woke and "uses it as a bludgeon". Virtually nobody describes themselves as woke at all except to point out they've been accused of it. It's a pejorative attack-term used to dismiss people and characterise them the way you're describe,
completely regardless of their actual behaviour or views. I've seen far-right politicians labelled "woke" routinely (you can't argue with this, unless you want me to link tons of British newspapers, because it happens constantly). Woke is to right in the 2020s what "fascist" was to left in the 1980s and 1990s. It's just a word they slap on people - even their own - if they think they are insufficiently far right.
Kind of ruined your argument immediately there, by buying into pure fantasy.
If you disagree with someone, that's fine. But don't label them with a dehumanitizing or demonizing term like "racist" when it's completely untrue
Except the problem is those last four weasel words.
Because in the vast majority of cases with people getting blocked they are, in fact,
saying racist stuff (which doesn't necessarily mean they are a racist, note, though it often correlates with that). They're just unhappy that it's characterised that way. We see this all the time - people come out with some lazy racist canard, often about Black-on-Black violence or the like, then they're shocked, absolutely astounded when people point out that what they're saying is racist.
And that last part is particularly sad, because watching these discussions, most of the time, what happens is this:
Person A - But [Racist canard]!
Person B - That's a racist canard.
Person A - OMGGGG HOW DARE U CALL ME A RACIST?!??!?!
Person B - I didn't, I said you were repeating a racist canard..
Person A - AAARRHHRHRHFHGHGHHGHGH YOUR STILL CALLING ME RACIST!!!! WHY ARE YOU WOKE LIBERALS SO AWFUL TO US HONEST FOLK!!?!?
Person B - Okay you're having a meltdown, and cannot be reasoned with, so I'm blocking you.
Person A - SEE SEE SEE THEY REFUSE TO BE REASONED WITH!!!!
It's pretty funny and pretty sad frankly.
