I agree with that. Just let them be .

I have gay friends and have just been invited to witness their marriage/wedding/legal union whatever you want to call it. I am proud to say that I am happy to do that. They have always been there for me. They took care of me when we were on holidays and when I was ill at one point. They are sort of like big brothers I never had, and they have never asked me for anything in return. They both have so much love to give and did a lot of voluntary /charity work at their own expense. Why should I care if they are both men?
