not as simple as that, gillymoor. for a start, opposition to redefining marriage is not discrimination. discrimination, for example would be refusing to serve homosexuals even when it involved no moral compromise [ as serving a marriage license might be seen to be ].      secondly it is now Christians [ or any others with faith related objections ] who are now discriminated against because of their religious convictions.
I expect the usual posters will call me a bigot, and I can live with that.       except for not doing anything that might seem that I endorse what is against my biblical convictions, I have perfectly fine social interaction with anyone, whatever their sexuality.
