Wow. It's a shotgun crossed with a speargun (you know usually linked to diving). Its not even close. You seem to be the type that just looks for things to get offended by.
Actually not. If you look over my posts you will see I am not usually offended. That it was a speargun was apparent on second look. What a shotgun has to do with diving I do not know. The confederate army was gray. (I actually have not trouble with them either. They fought for who they identified with like most soldiers). My only issue is with some groups who have appropriated the symbols for their own purposes many years later. But that is not related to diving.
The OP ASKED what we thought about the artwork. That particular piece of art work at first glance looked like it was talking about the CSA. A logo or any other symbol should send the desired message at first glance. In my particular case it did not. I answered the OPs question.
So what is Carolina Steel? Is it a sporting good store hence the shotgun and the bird? Is it a T-shirt company? Not obvious at first glance.
