Oh, sure, absolutely. But I couldn’t be in a relationship with somebody for whom those were dealbreaker issues. It by no means indicates that I’m not tolerant of them.
If a couple doesn’t both oppose abortion, she may kill your kid.
If a couple doesn’t both oppose open marriage/swinging, she may want to “play” with a partner of the same or opposite sex.
They can become “deal breakers” real quick. They don’t just come up at the ballot box.
And there are plenty people on the dating sites that meet both of those scenarios.
I find them more significant than which party someone votes for (unless they espouse love of Communism which a number actually do have a positive opinion of the ‘c’ word).
