Yes, I do. Or I just wonder whether anyone would agree with that, rather. I'm not exactly sure whether that would be a good analysis.

Things have changed quite a bit. Society has changed. I wonder whether something considered delusional to some (small) degree is now more acceptable than it used to be.

The assumption is that many would mean by delusional is only different in degree from real or more severe delusions. BP could be an example of a high degree of delusional thinking, but in itself, already less severe than some forms of psychosis. So an even lesser degree would be BP-like, if there can be different degrees of the (exact) same thing (or essentially).
