Cute, glad you like my friend’s band. FYI, they pulled that symbol off a Japanese Anime cartoon.. so much for reading so much into things.
Interesting that you think it cute and that you think I like your friend's band.
Don't know how you reached those conclusions, but I'd say it is completely consistent with the images displayed by your friends, denying the existence of evidence for God in nature and denying the importance of Biblical numbers for understanding Christianity.
I suppose the thinking that anything displayed in Japanese Anime is therefore harmless is consistent with those thought patterns too.
