The whole thing with parenting is there are parents who make choices for the kids until they're old enough to make them themselves.
Parents try to provide the safest, most loving environment they can for their children. For example, they may attend college, establish financial security, get married to a person who shares the same world view, establish a college fund, get some standing in the community, whatever...then they start a family. They do what they can to provide for their child's needs and try to avoid situations which put their child at risk.
CHILDREN DON'T GET A VOICE. You can't ask a kid what he wants if he's an infant. Kids who are 10 years old don't know what's best for them. These are the tough decisions that come with being adult and being a parent.
I've no doubt you would never choose now at this point to have any other parents. That's great, that's wonderful. But the point is still the same. Your parents knew you would suffer because of their lifestyle, and they made the decision to sacrifice your peace of mind, safety, happiness, whatever the risks were, because THEY wanted a kid.
You came second to their desire for a child.
