I was diagnosed with ASD, and I've come a long way towards passing for normal in social settings. I'm still quirky, but generally in a good way rather than a disturbing you-have-a-problem sort of way.

While I agree that people on the spectrum should try to master social skills and interactions, it's also important that people are tolerant of the condition. Just as with any disability, both sides should want to maximise integration into society.

As for disapproving of those who don't try, while I have some sympathy for your point, it's important to remember that it's a spectrum condition. What might be achievable for one person could be impossible for another, depending on the severity of the condition. It's very hard to know how much effort a person is making without knowing them very well indeed.

Finally, it's also worth distinguishing acting normally in social situations from trying to change yourself and your personality. No-one should be expected to be 'more normal' as a person, except where their lack of typicality is harmful to others.
