Autistic Family Member Saying Weird Shit

There’s this autistic men in ny family and I’ve heard him say an inappropriate comment that made my blood boil twice…He said “when I have a daughter my daughter gunna be sexy my son gunna be fine as fuck too” 🤮🤢 I got so angry and told him “wtf makes you think it’s ok to refer to children as sexy that’s not ok AT ALL” he said is not like that I don’t mean it like that I’m not that type of guy you know I’m not that guy that’s not how I meant it I was just stating my opinion on my future kids looks I understand it bothered you but I don’t mean it like that you taking it in a bad way” I didn’t care about none of it I told his mother and his sister and they got on him specially his sister but the mother it was like she had to explain it to him like he a damn 5 year old and don’t know that’s wrong they had to break it down to him…and then he understood mind you this man is 30…Is it normal for autistic people to say weird things…This really angered me!!
