While “self-styled” seems mostly a put-down, it is a notably weak one. The user of this phrase notes that someone claims something, but lacks an official credential, or strong consensus, supporting this claim. But we the reader can also note that this speaker offers no stronger criticism, and is not willing to directly contradict the offending claim. After all, instead of calling someone a “self-styled visionary,” you might say “he calls himself a visionary, but he’s not; he hasn’t has a vision in years.”

I admire grand ambition, and think our society relies way too much on uninformative official credentials, that tend to signal status affiliations, social-savvy, and generic impressiveness more than specific relevant features. So if someone goes out of their way to flag that they dislike some presumption of yours, but aren’t willing to actually disagree with or criticize your claim, I’d call that a pretty good sign about you.  Go ahead, be self-styled.  To my style eye, self-styled is more stylish than credentialed.
