Maybe set aside the accusations in the first paragraph that depend on me not agreeing with your second paragraph. The second paragraph is an argument I have made many times and I still make today. In fact it's one of the main reasons I voted against Trump in the primaries.

That isn't the end of the story, however. Patterns can be evaluated for meaning, and more importantly, actions can be evaluated. But you're totally right, it is very hard, if not impossible, to get a firm grip on what he is actually going to do at this point in time. It's a big reason I did not vote for him when there was a better option.
