I get what you are saying, but nearly everyone who has ever lived is full of baggage. After a certain age, any relationship you start will involve talking about all the bad shit you both experienced, how it affected you, how you've grown and dealt with it, etc. Just be an adult about it.
What matters is whether a person who had a bad past is willing to put in the effort to deal with it. A former heavy drug abuser who sought out some form of treatment or has largely healed is a fine partner. A partner who is still sneaking out and stealing to get their fix is much less so.
It's really really easy to just not hold someone's past against them too hard if they are demonstrably a better person currently.
Yeah, but thats the point. How should I know. Its a matter of trust. If you have made decisions like that in the past, why should I trust you to have changed? People are deceptive. Better avoid the drama altogether.
BUT
When I dated someone in the industry I quickly realized why many people avoid such workers. It's highly correlated with HEAVY drug use, severe mental illness, and sad family stories. Not challenges lot of people looking for in a relationship, especially if they want children.
