Sounds like a bit of a cop out. "I refrain from doing this thing that gives me social anxiety - not because of the social anxiety! - but out of respect to others." Uhuh, sure...

There isn't anything wrong with not wanting to socialize (unless it's causing you numerous personal issues, AvPDers and Schizoids). There also isn't anything wrong with not wanting to be particularly outgoing. But if you want to engage socially with others, to make friends, then you've gotta make an effort. At least a little bit.

I have no doubt that some extrovert will eventually come along and adopt you as a friend. They might even be a very good friend. Or it might be me.

However, and maybe this is only my personal gripe, but it isn't my responsibility to somehow recognize that the wallflower secretly wants a friend, and then to pull them into conversation. If you're not engaging in conversation, I'm going to assume it's because you don't want to engage, and I'll respect your boundaries (more or less).
