Really? Then why is it not socially acceptable to judge others based on race, religion, sexual orientation, looks, etc.? If people allegedly have the right to judge and treat people however they please, then you'd think racism, homophobia, etc. would be acceptable. But they aren't.

No, the truth is that society at large believes that people like me (socially awkward, lame, cognitively slow) do not deserve respect the same way others do. And anyone who cannot see that this is wrong has no moral compass.
