Reality: There have been people who’ve experienced Genetic Sexual Attraction who were unaware of their genetic relation and had never heard of GSA before.
Trying to blame people for experiencing GSA can be like trying to blame someone for where they were born.
Sons and daughters had no control over being placed in the circumstances that resulted in GSA. Siblings usually didn’t either, although there are a few situations in which an older sibling, especially a half sibling, chose to be away from their younger sibling during the critical years of childhood, but it’s not immoral to, for example, go away to college or relocate for work or pleasure. While it is nice for family to visit, an adult older sibling has no moral obligation to make sure they are around their parent’s youngest child enough to ensure GSA doesn’t happen.
Genetic parents are more likely to have some control over the circumstances, but they don’t always. Some of them don’t even know they have a genetic child “out there” until that child, now an adult, shows up on their doorstep or in their online inbox.
