i think we need a policy where people start to understand problems as human issues, that ALL humans can experience and not issues related to a particular group. e.g. "but that's simply not possible if the managers or HR personnel are religious conservatives".
That's not possible. Religious conservatives are fundamentally opposed to same-sex relationships and non-monogamous relationships. If they're not, then they're not really following their religion and they're not really conservative. You can't have it both ways.
People who are already and admittedly prejudiced against others, for things like skin color or relationship type, cannot be trusted to be impartial.
And Jesus ate with people he considered sinners and treated them with more respect and dignity than anyone. Your argument is bullshit. The only fundamental difference between people like you and the Westboro Baptist Church is who you think it's okay to discriminate against.
That's not true. I know lots of religious conservatives who don't care about any of this. I'd probably even say that the vast majority don't care about these things.
You can't no true scotmans them out of this. If someone identifies as a "religious conservative" then that is what they are.
You can put aside your personal views at work. I don't give people shit or favor for their views in either direction. It's called being a professional.
If you come to a manager who's an anti-LGBT crusader outside of work with some issues related to your same-sex marriage, if you really think that person is going to give you a fair shake, you're insane. They may try to hide their views so they don't get fired, but it absolutely will affect their treatment of you.
Exactly: in each of those situations, your virulently anti-LGBT manager or HR person will find out what you are, and then use it against you in overt or subtle ways. It's hard to hide your lifestyle at work.
