That's all besides the point. You can make the same argument saying: "Some people are attracted to ugly people."
The "you cannot make any statements at all, as there might always be at least one exception somewhere" just doesn't fly.

Now I agree there are different flavours of 'shy' and some can be attractive or associated with other attractive traits. And yes, you can also be too extrovert, outgoing. But you don't want to have that debate. You just want to shut it down. Why?

Also, it contradicts your post on the top of the previous post. Maybe some people (I am too scared to use 'woman' even though that is the obvious context, hest I be a sexist.) are attracted to people that are unable to connect emotionally. I mean, there is no collective knowledge about what people choose? Right? So people can never learn these things, period, even if they wanted. No way to know. Being nice, communicating well, some may like that, some may hate that. It is all arbitrary and random.
