I do not understand why you would bother to care that a Xtian is mad or does not like the fact that you claim to be a Satanist.

As far as I remember, to be happily accepted by other religions is not the point of Satanism dear.

Besides most Xtians are stubborn and put up their noses to things that are immoral in their minds.

Don't fret about it. Instead accept that the lifestyle you have chosen as a Satanist separates you from the majority. Enjoy that you are different.
