You don't.
We all hate disloyalty, being lied to and being cheated on so it isn't your place to cause heart break for someone, even if you don't know them. We're human, we all have feelings and sometimes we can't control who we fall in love with, but we can take precautions and we can take a step back from someone who's taken, to prevent causing pain to someone else.
If you see someone you like the look of and you're interested in making a move, but you soon find out they're taken, don't make a move and don't ever believe you'll make them fall in love and leave their partner for you. That's an incredibly narcissistic and selfish thing to believe. If you ignore that and make a move and they do leave their partner for you, that person clearly does not respect the idea of commitment and are easily persuaded, so who's to say they won't be taken from you by someone else if you start dating? That concern will be on your mind constantly.

You should always be respectfull of other people's relationships. They've worked hard to keep their relationship running smoothly and happily, so it's unfair and selfish to barge in and ruin everything for them. You wouldn't like the same being done to you and your relationship. There are millions of other people who aren't in a relationship and are actively looking for a partner so you should always date the singletons and avoid the drama!
