You're being asked to participate in what your religion refers to as an unholy ceremony. According to the Christan faith, only male and female can be joined together in HOLY matrimony and be made one. Anything other than that is considered an an abomination - a very very sinful act. No one should be forced by law into committing a sin against their conscience and against their own immortal souls.
Agreed. However, homosexuality notwithstanding, the right to choose associations is the hallmark of a free society.
Which is why this should not be merely a debate about whether homosexuals can force me to come to their wedding; we need to make this about the broader issue - true freedom to choose.
We will not win the hearts and minds of the populace by making this merely a religious argument...
