I did answer your question. I would say that I am here to register as a Muslim as the unconstitutional president requires. I would neither affirm nor deny my Christian faith. 

My Austrian and Czech Jewish relatives, including my mother's parents, had to register as Jews and wear the yellow star of David. For me not to support my Muslim brothers and sisters would be denying my own family, murdered by the Nazis that Trump would be emulating. It would also be denying what I believe my Christian faith would have me do.
