Why I never!

No one is asking you to.

Literally, no one.

You don't have to watch. You don't have to come to the wedding. You don't even have to come to dinner.

But, you do have to respect people's rights. Because in the end, how does what two people do alone in their bedroom have to do with whether they deserve basic rights?

And when all people have basic rights, to work, to not be harassed, to build a legally solid marriage and family, to participate in the economy, society is more stable and we all benefit from that.
