I dare you to name one person who has actually been "cancelled" for any reasons other than publicly, repeatedly, expressing their hatred of others or sexual violence... and even then, I've yet to see it be anything close to permanent (e.g., Louis CK just won a Grammy). It's a conservative/right-wing whine with no connection to reality. That a bunch of older male comedians have co-opted it as their own whine why they're afraid of telling certain jokes or addressing certain topics doesn't do much for its validity.
Though I'm sure you meant well, following my genuine frustration with the rise in anti-semitism (not just on the internet but it's played its part) and the general acceptance/promotion we've seen in public the last few months, what you said comes off as patronizing and privileged. Some of us don't get to stick our head in the sand and pretend it's not happening (really nobody should), nor both-sides the hate as if the left and right are equally to blame here. Kumbaya certainly won't stop the bigotry. I agree that it's exhausting.
