No. All of human moral progress can be briefly summarized as "not hurting other people". Solving disagreements through discussion is better than solving them through violence, but you don't solve disagreements via discussion if you attack them verbally.
Absolutely: I am accusing you of either that, clouded thinking, or both.
In fact, this discussion is a demonstration of my point. We are both attacking one another's intellectual and moral reasoning abilities via speech. This is better than than us having a fist fight over the matter.
Right, and because it's hard to have discussions that may not be easy to resolve, it far easier to re-label those disagreements as "attack them verbally." Hence, the new thoughtcrime.
