T99's point is well taken. Easy to say Of course we should express our opinions. But let me be contrary for a moment. (Quelle Surprise, eh?)
Clearly, the wrong people are speaking up. We are awash with people who don't realise that no one asked them.
This gets tricky, on both fronts. There are people who will resent me speaking up, because they expected in their entitled way to be unopposed. I will often jump in simply because I discern that a person deserves some pushback. These seem to be much the same people who are willing to insert their political or social opinions gratuitously, don't they? The rules flow only in one direction?
Or maybe it's just me being a jerk. Nah, couldn't be. I once jumped on a person at Sunday School who pressed her point by beginning her counter-counter-argument with I don't mean to attack the sincerity of anyone's faith, but... by interrupting "Of course you do. That's your whole point, and I resent it."
I think we should be alert to giving offense, and asking ourselves whether whether it is worth it. The cheap virtue signalling that I object to are most often people who have not actually thought what it would be like to hear their words. They are plumping up their virtue at the expense of others.
There is nuance and context, situation to situation. All very amusing to contemplate, but not to discuss.
