Because the majority of people who believe that gay people should not be allowed to legally marry base that on their personal religious beliefs. Not all, of course, but the vast majority.<quoted text>
Of course, I would ignore religious belief as a protected class, in what way, shape or form is it even remotely related to the point that I am speaking about?
I am debating your statement on attraction and laws, forgive me, but how is religion even remotely related to that topic?.......
Religion is intertwined into the debate, and has driven it form the start.
If you simply look at the pros and cons of same sex marriage, it's not hard to see what drives the argument. Even in court cases, where they anti-marriage folks were trying to come up with some non-religious reason to prevent SSM, they were unable to do so, and in some cases, freely admitted that SSM was not harmful to society, and was good for the couples and families involved.
That leaves only religious belief.
And another person's religion should not drive the civil rights and basic freedoms that those that don't share those beliefs should receive.
Thus a hundred court cases.
