I'm equivocal on both of these.
In the case of (1), why should the act of fighting injustice pause by some notion of decorum at work? Where should our priorities and values lie?
In the case of (2), many people have good reasons to find the prevailing leftist/progressive rhetoric distasteful. But right now the groups who espouse that rhetoric are also the most active and most effective groups taking action right now. If you aren't with them, who exactly are you with? Or so the rhetoric might go.
