Would you, a secular person, be against cheating?
Why? How do you justify it without religion?
And then, could you possibly forgive someone who would cheat on you in moderation (in other words, not compulsively)?
I just thought about that today... I'm not a particularly jealous person. I think that besides developing an emotional connection with another person and running off on me, I wouldn't really oppose it in my partner...
Anyway, what do you think? I'd like to get the debate going.
