Is it OK to discriminate against Christians (on a dating site)?

Just for fun, I was looking at the questions on one of those internet-based matchmaking sites over the weekend.

Among the dozens (maybe even hundreds) of questions, were several having to do with religion – what is my religion, what religion should my potential match be, etc. There were other questions that dealt with intensity (fervency) of religious belief, etc.

You can also make a determination of how much weight a given factor (in this instance, religion) plays in the match-making.

That got me thinking. I know that I would not be a good match with christians – and the more fervently christian they are, the less likely I am to have anything in common with the person.

So if I were to fill out the forms, I would say “pretty important that the person NOT be Christian”.

Is that ethical?

Am I discriminating (or persecuting) Christians by saying that they are of no interest to me?
