As I've said before:

Leftism is a Philosophy of War. Leftists seek to seize power from non-Leftists and to enforce their will upon non-Leftists because they are considered enemies. All enemies are outside of your moral framework, which is why it is not immoral to murder them.

Your enemy is not effected by moral force, that is why you do not give moral consideration to them. That is the reason you have to shoot at him in the first place. All other forms of force have no effect upon an enemy.

Now, in fairness, before any FBI agents start commenting in replies, no you can't just go full helicopter mode. You can't fight the same tactics as your enemy because you aren't fighting from the same position.

The thing you do have to recognize is that a moral judgement by a Leftist is that it is the moral judgement of your enemy. Never give it the time of day. Operate in total obstinance to their demands, and let them hurl themselves upon the earthworks. We are operating from positions without institutional strength, as such, we need to rely on building our own institutions, gate-keeping, refusing negotiation, and infiltrating into their own systems to disrupt them.

We win by focusing on our advantages: we build perpetually, we gate-keep aggressively, we refuse to obey, and we must be prepared to forgive and grant mercy upon repentance. These are tactics that the Left can't replicate, which is our strongest advantage.
