His argument has merit in terms of making the comparison. There is logical consistency in what he is saying and the comparison he is making. I am not speaking to the content of the message, just the basis on which he is making it. You have several times made broad statements about Nazi's based on the policies of the extreme few (relative to the population of Nazi Germany). If you see someone wearing a swastika, I bet you make a boatload of assumptions about them and not a single one is positive. The fact that you see someone wearing a cross and don't assume a ton of negative things about them is likely more a product of your view on Christianity. That is not my opinion, that is an observation.
