I don't necessarily think his writings are a crock. I haven't read much of his work, but I read Paths to God and found it enjoyable. Largely, I guess I'm trying to contextualize judgement vs. non-judgement. If you're saying you can punch someone's lights out without judging them, my interpretation is that you're going through some process like this:
1. Suppress emotional judgement. (Maybe do this by re-framing their actions as something that is the way it is, like a tree or a river)
2. Evaluate the situation with a calm mind
3. Come to the conclusion that their behavior is undesireable in one way or another
4. Decide that in order to dissuade them from behaving that way in the future, you should punch them in the face.
5. Punch them in the face
I think it's probably a reasonable goal to insert a "stop and think" step before doing drastic things like punching someone in the face.
But I also think there's a non-negligible effect from using your emotions (in this case, the emption of judgement), to propel you to actually take action. I think it's very unlikely people are spurred to action by something that doesn't move them personally. There's just a bit of difference between "I'm mad about Trump. I'm definitely judging the hell out of him." and "I've come to the conclusion that Trump is a suboptimal president." I think a person in the former mindset is more likely to actually take action.
And again, I think in the context where people are too judgemental, and spend a bunch of time unproductively stewing about things, Ram Dass's advice to remove judgement is a good corrective.
