Normal people dating down syndrome
Not all people with Down's syndrome have diminished capacity to the extent you are suggesting.
It very much depends on the individual, and your judgement.
She is still a person with feelings exactly it's all about ' Mental Capacity' in it's legal defintion , if someone with downs ( or any other health issue ) has sufficient understanding and mental capacity then there is no legal or moral impediment ...
i think what op is getting at, is whether or not it is exploitative or taking advantage of the girl who may not have the same level of maturity to consent to this.
She really wanted a bf and hit on quite a few guys but no one would date her. but then due to her diminished mental capacity I wonder if someone with full mental capacity should not be dating her ....., in the way most people would say a 20 year old guy shouldn't be dating a 13 year old girl because he's mentally much more developed than her and could be taking advantage Oh I kinda see what you mean now I think it does depend to an extent on the specific situation.
Just because they have down syndrome doesn't mean they're a complete and utter idiot who should be banished to only date others like them.
she's a human being and therefore has liberty to do what she wants, likewise with the guy.
I saw some pictures some time back which went viral of a guy taking a girl to a high school prom, the guy was good looking and normal, the girl had down syndrome In one of the pictures the guy was in a passionate embrace with the girl.
Apparently the guy was in love with the girl and this was backed up with quotes. I would have thought this sort of thing would be illegal due to her diminished mental capacity. Not all people with Down's syndrome have diminished capacity to the extent you are suggesting.
I think it depends entirely on the individual's abilities, what they can and can't do and can and can't understand.
Other than that, sounds quite sweet to me And unless you're taking advantage of someone, I can't see how it would be morally wrong or illegal.
whilst I am sure it would put other guys off, it is really none of their business.
