There surely exist people such as you describe, but I think they're far less prevalent than you might worry. Amongst techies I know in the area, maybe 40% have at least one of the negative (from your perspective) attributes you've listed; I don't think I know anyone personally to whom they all apply, and "the type of person who likes eating meat, drinking beer, talking about politics, money, science, entrepreneurship, programming etc." could describe most of my friends.
