I'm not a "flag shirt" wearing kind of guy, but it doesn't bother me if someone else wants to wear one. The problem I have with this is, if you take issue with someone having patriotic pride, on the 4th of July, Cinco de Mayo, or any other day for that matter, find your way back to where you came from. Permanently. We didn't ask you to come be a part of our land. You chose to come here. If I moved to Mexico I wouldn't get offended to see people wearing Mexican flag shirts on the 4th of July. I'm sick of people getting offended over petty things. Suck it up, be an adult, and deal with it. This should never be grounds for a lawsuit.
Two wrongs don't make a right, but three rights make a left.
