They say that it is a pagan holiday and that it is a sin. "God doesn't like this," two women told me yesterday.
You answered it well. If I were in your place I'd argue by asking them who actually created GOD? Did God even know that he's having so many names that it's almost impossible to remember them all. Did God existed pre language era? I'm not atheist but I believe it's God who created the world and us but it can't be God who filled it with do's and don'ts, this or that, sects, religion, racism, festivals, propoganda, wars, nukes .... Fuckin' creativity of man has led to a discrimination with someone who created the Universe.
