Agreed. I am ok with people riding motorcycles without helmets or people riding without seatbelts. The science is extremely clear, if someone chooses to be stupid, they are free to do so. I am not ok with someone driving drunk, because now their decision infringes on my and others safety.

AA is not saying that someone cannot ignore science, be foolish and potentially harm someone else. AA is just saying they can't do it on their airplanes.
