You're doing the right thing. There is a clear-cut line between right and wrong, moral and immoral.

To the OP -- you really need to read the terms of usage that you agreed to when you signed up to this site. Couching sick posts as "it's depraved and filthy" or "so childish, right" doesn't make it permissible or funny AT ALL.
Also, making fun of mentally and physically disabled people is pure assholery. That you think you have the right to abase people that way is wrong, so wrong.
