No one is trying to change your opinion
But when you start name calling to try and strengthen your disdain for that part of the country, whatever that means, then you make it sound personal. So if you wanna make it sound personal, don't get all up in arms when people get personal back.
Which goes back to my earlier remark that it's your schtick. You think by saying the stuff you say that it gets people upset, but when they call you it on it, all of a sudden, they're being sensitive. You can't troll people then get mad when they call you out on it.
