The easiest way to get an argument started here in Ft Worth is

A - Tell someone where the best B-B-Q can be found

B - Tell someone where the best Tex-Mex food can be found

C - Tell someone that chile has/doesn't have beans in it

PS - The answers to the above questions are Angelos, Benitos and it really doesn't matter that much as long as you have something cold and wet to wash it down with.
