Not this NT.
Considering that NTs are a majority of the world's population, we're pretty diverse, so I know that everyone, including the people making the criticism, recognises that there are some decent people mixed in with the crowd. So I don't take it as criticism of me -- I do my best to be one of the decent ones. If anything, my reaction is just the opposite of what you suggest -- getting to know how much hurt there is behind the criticism, and this is something I've only really found out since joining WP, makes me all the more want to do what I can to support you guys, if you'll let me.
Of course, this comes from a rather biased perspective, since my girlfriend is AS, and since discovering that I've come to realise how well that fits in with all the traits that make her such a wonderful and adorable person; so I'm pretty sure nothing could ever make me join the "cure for autism" camp.
