How is legalizing gay-marriage against freedom of religion?

[mikegriffith1]

Do you agree somehow? Isn't the whole point of freedom of religion to be able to practice own religion (or not at all if atheists)? How is a gay-couple, who want equal freedom, marrying obstacle anybody's freedom to religion? It's not like legalizing gay marriage means making straight marriage illegal. conservatives argument against that is "it's against religion" is quite reasonable.

I take it you have not seen, heard, or read any news on this issue for the last two years?
