Okay... I think I see where you are coming from. Yes, I did misunderstand the meme because I didn't know any of the background. The Facebook page didn't give me a lot of information but it did give me enough. Apparently the Sikh are defending other people, probably from Muslims. That is why it said they are defending all faiths.
Your meme is from the point of view of the Sikh police office saying that he is "...so Sikh of this sh...". I originally thought you were confusing Sikh with Muslims (as has been done in America too many times) and you were saying that you were "Sikh" of all these Muslims or something like that.
I apologize.
