Well, I have given up on all but a few INFPs. And there were one or two ESTPs that made me dislike ESTPs, but then some of the others made me think they were exactly the kind of person I'd like to meet.
So, I dislike INFPs, and overly moralistic/boring/past-centric ESTPs (unless of course they're really ESTJs).
If it comes to it, the one type I'd give up on would be the ESTJs. This is only because of certain experiences though. I wouldn't however give up on them unless they are following the stereotype step by step. And though the stereotypes aren't many, there still are.
If you could be anything you want, I bet you'd be disappointed--am I right?
