I'm fully aware of what it resembles and I agree 100% with your statement. I guess I just gave the OP the benefit of the doubt to assume that they wouldn't have the audacity to reference a marijuana leaf in this scenario but it appears that they did.
You absolutely have to be trolling.
...Right? The remainder of your post after that statement looks so serious that I'm confused.
Regardless, come on people, saying the leaf could be replaced by something else that looks better or generally fits the set more appropriately, fine, but being offended with its usage? It's 2016, the set's obviously not serious nor meant to advocate drug usage. One of my Abigail Williams shirts has an inverted pentagram on the back of it and reads "Under Hell, Under Satan", my ultra religious Roman Christian grandmother who is 83 years old thought it was funny. Obviously I do not worship Satan. Please.
I don't think anyone should impose such strong frowning upon something that's as tame as this is just because you want to stand moral high ground. The mods pack isn't going to come with a complimentary packet of cocaine, it's a picture of a leaf that resembles (obviously intentionally so) a marijuana leaf on a Jamaican themed set. Mercy.
