My argument is that it is my churches responsibility to speak out not against everyone as if we are the morality police but as concerned neighbors who want to encourage dialogue in this area.
We are talking same-sex marriage and we are talking about legally consenting adults.
When a right enjoyed by all others is denied to classes of people based solely upon
common human constituents like skin color, gender and sexual orientation then this is bigotry. It is not necessary to have malice in your heart or have a cross ready to burn on the front lawn. Such exclusions are bigotry prima facie.
Part of the sinister nature of bigotry is that so many of its practitioners confuse their bigotry with simple differences in moral opinion. Denying common human rights to human beings is not some simple difference in moral opinion. It is destructive and anathema to the entire concept of Human Rights. And when it is done to an entire class of humans based upon some uncontrollable common human trait it is destructive and anathema to the entire concept of equal under law. It does not matter the reasons, the justifications, the platitudes. It is bigotry.
Do people, churches, organizations have a right to express their differences in moral opinion? Yes, of course. The skinheads have every right to march through the streets with their swastikas. And the rest of us have every right to see their bigotry for what it is. Religions have every right to teach and hold their congregants to anti-gay traditional-marriage doctrines. And the rest of us have every right to see
their bigotry for what it is.
Is it bigoted to have a supported opinion?
When that opinion seeks to deny common human rights ... Yes.
