Why do people say the past doesn't matter but it actually always dictates compatibility?

[Anonymous]

When you meet someone for the first time, you hardly know about them and the past always shapes the person in front of you now.
Both can have a promiscuous stage. Sleeping around isn't the problem, the problem is both men and women want someone who didn't after their fun time is over. But actually, they are compatible with each other and they should date each other. People with no promiscuous past will judge and consider the past as problematic, whereas people with a bad past will see the clean past of other people as attractive.
So the past plays a role...

Sure the past does shape you in some form but at the end, it does not define you. It's not your business to know everything about someone elses past, unless it has something to do with you
I don't tell everything about mine, I would only tell some things like trauma , when I'm comfortable with that person.

Hos are telling guys that their past doesn't matter, but once a ho, always a ho.
