My agnosticism has nothing to do with pointing out other peoples' stupidity.
No one knows for sure what he believes deep down. I can't really call him stupid for saying bho is anymore than I can call you stupid for saying bho isn't. I can see why people would think he MAY lean that way though.
With his pattern of using separation of church and state to squash Christian religious symbols yet not doing the same for Islam, surely you could see there is some hypocrisy on his part and also see why one might think that, even though it isn't conclusive.
Again, not saying i think he is but I am saying I could see where people might think it without them being "stupid".
