Do stereotypes have any truth to them?

My favorite is 'atheists have no morals'.

Yeah, that's certainly not justified. Lots of atheists have morals.

It's true that a lot of atheists think that morals are simply social conventions, with no objective existence. But even if a person believes that, he can still do his best to obey the conventions of his time and place. 

There's another stereotype concerning atheists I see occasionally. People who study theology seriously will make fun of what they call "Reddit atheists." These are people who 1) talk a lot about religion on line, and 2) have enormous confidence in their own reasoning power, and 3) know little or nothing about theology. And of course until quite recently they often referred to the works of Dawkins and/or Hitchens. 

This is the sort of person who thinks he has any and every Christian check-mated, while not bothering to learn much more about Christian thought than "TalKinG SnaKES!!1!" "NO MaterIAl EvidENce!!!!!"

I think we've all encountered people like that, but Reddit atheists are surely not representative of most of us. They are on line and visible by definition, while the great majority of atheists don't care enough about it to go on the Internet every day and criticize.

(Bold mine)

The implication here is that there are at least some atheists who have no morals. Could you please list some of these amoral atheists? Bet you a shiny shilling that you can't.

But what a sly boots you are, perpetuating a stereotype like that.
