Is dating your step-sibling incest?
What do you think?
I'm only asking it because this guy in my year is dating a girl that his mum is dating the father of. If their parents get married, they'll be step-siblings. But since they're not really related, that can't be against the law or anything, can it?
It does seem a bit weird but only a few thousand years ago, pretty much everyone was marrying their siblings and only 100 years ago, it was pretty common practice for an uncle to marry his niece. Is it incest if you're not blood-related? Is it just morally wrong? Or is their nothing wrong with it at all?
