Keep in mind who it was that pushed the "don't judge a book by its cover" motto.

Before the hippy 1960s, most school hygiene films made a point of telling you that, your appearance reflects how you are on the inside.

One of the worst books to ever be introduced into the American school system was To Kill A Mockingbird. Not because of any racial aspects, but because of the fictional character Boo Radley.

The weirdo at the end of the street should not automatically looked at as some misunderstood and benevolent figure. Instead if the reason they are looked upon as strange, then there is obvious reason to be wary of them. They may be fine when you get to know them, but there is a reason for trust to be earned instead of given.
