Dating for downs syndrome
So in theory you do have shades of Down so to speak.Legally as long as she is of age he should be fine.She's not fully Down Syndrome (though has a carer) more like 30%ish Downs. I don't know for sure but I do know that some people with downs are capable of living alone and caring for themselves and they do have relationships.
IMO that would be 'cruel and unusual punishment' Everyone deserves good lovin' Down's Syndrome is an all or nothing condition. If the chick is legally an adult by age AND is legally competent to make medical decisions for herself, then she's a consenting adult like any other.They are caring and loving and also able to take care of them selves.
