By saying it "depends on *Who*", I'm was looking at this issue from a Political Liberal/Conservative POV.
>>If the guy had been a "Libnut" (as I politely call em') & wore a shirt say "ALL 2A Supporters are Killers", then I honestly believe that he would've been given a Free Pass & most likely been regarded as some kind of Hero.
>>But he doesn't appear to be any of that, so my take on the situation stands, that the wearer beware of who you are in present company with when making Any Pro-Gun Statements.
>>As far as *Suing* is concerned, there again, I believe That would be a waste of time & $$, due to the general fact that most arenas of the Gov't appointed System (today) are of the *LibNut* nature & the case would be thrown out for being Frivolous & Unwarranted.,
Just MY Opinion not being a Lawyer or any kinda' expert in the matter.
You are right there, he was not encouraging a Vote Pro or Con, but the "Essence" of the shirt was most definitely in favor a positive POV on 2A, thus the outcry of the Naysayers about Any 2A presence at the Polls on That given day.
