What's your point about Muhammad Ali ? Cause someone who's rude with the waiter but nice with him wouldn't be a shapeshifter... a shapeshifter would know exactly how to play nice with the waiter as well, even though it would be all a trick to make people think he's nice.
My "standards" (in terms of relationship) usually make me attract people who are actually interesting because they're not trying to reduce themself to other people's standards by attracting whoever for the only purpose of this feeling of social esteem some are so eager to find anyhow. But I don't have any "standards" when it come to understand other people. And I don't like assholes, you're the one giving them this name, I'm talking about shy or rude-at-first-impression people, people who don't intend to attract you because they don't want you to like them because they're not interested in your opinion of them, and even if they are, they're going away from it one way or another or use this information in their own way. But they're not assholes. Assholes are people who attack and belittle on purpose, we can find assholes being on both side here, that's not the point.
Oh and also I'm not talking about girls only, some guys can be like that.
Now I have to say, the "Beta" thing is totally boyish, like you only have the choice to be either dominant or suffer a shitty treatment from the dominant ones. That way of thinking is exactly why some boys and girls are being "rude" with your kind of people. I mean, maybe you enjoy playing this game of "who is the most dominant here who can freely be mean with the others" etc but some just don't like it. I've seen both side you know, I've played this Alpha-Beta game plenty of time, sometimes it's fun, even though you "loose" but it intend to be exhausting and I don't find it hard to understand why some people rather be rude to others instead of drowing into their little game of thrones or whatever.
Also, there's not "one" type of self-overprotective just like there's not "one" type of "socially attractive" people, there are dangerous and nice people on both side, that's all I'm saying.
Let's be simple, my point was that being hard to approach doesn't necessarily mean you're mean but just over-protective of yourself, and, on the same train of thoughts : being easy to approach doesn't necessarily mean you're nice because you can (girls and boys included) be an asshole inside and have learned how to hide your true self anyway, that's it.
