Well bless your heart. It sounds like some southerner crapped in your wheaties some time in the past.
Right, just dodge the point. Seriously, if there's the claim "oh there's assholes everywhere" then southern hospitality doesn't exist. It's only a title for them to claim that they're morally superior to northerners which is obviously not the case because you don't preach how nice and awesome you are when you do something nice for someone. You just fucking do it.
