Sadly, some people think its perfectly acceptable to say 'i just don't agree with homosexuals/gay marriage etc as i am a christian/muslim/religion x'. Its not acceptable to use religion as an excuse for ignorance. Such stupid comments in a few years time will be treated the same as 'Im sorry, i just dont agree with women working' or 'Im sorry, black/asian people - i just don't agree with them' are today. Whilst being more 'mainstream' a few decades back, they - and the people who say them are now viewed as primitive and inexcusable.
