Depending on what one person did and whether that person authentically changed and no longer committed another offense, I don't mind dating such people.

as long as the person didn't do anything that hurt human rights (right to live, right of freedom, etc.), I think I'd still consider them datable. So, no murderers (duh!), rapists, kidnappers, pedophiles, molesters, animal abusers, etc. I know animal abusers don't exactly hurt human rights, but still - inflicting pain unnecessarily is also a taboo in my world.
Also repeat offenders are a no-go. Means they can't change.
But someone who got caught shoplifting in their teenage years, is still OK.0
