What a stupid thing to say. If I walk around with a SHARK WEEK T-Shirt on, am i guilty of instituting panic? Or how about an OBAMA SUCKS one?
WE are not RESPONSIBLE for the IRRATIONAL fears of OTHERS. They OWN those fears THEMSELVES....and should seek professional treatments, ASAP.
T-shirts do not generally kill people (at least while being worn). So the fear of a t-shirt in that state might be irrational.
Not take that t-shirt off, and present it in a way that indicates that you are ready to strangle someone, and now we are no longer in the realm of the irrational.
It's not just the t-shirt. It's the presentation.
