Would you consider it inappropriate to wear an Isis band shirt?

this band

I don't own any, but despite seeing discussions of this, I'd say no. Their name long predates the group so there's no problem. Not to mention I've seen people wearing shirts of bands with these names before.

No, but its just unfortunate timing.

One of the Mardi Gras krewes was named after the Egyptian god ISIS (most krewes are named after ancient deities); the members had to change the name because they were being harassed when they wore their t-shirts.

Absolutely not. Anyone who thinks a person just walking around the streets of America is a terrorist who is openly displaying the fact that they are must be stupid.
