What's the harm in this person recognizing that their autism plays a role in their enjoyment of specific activities? If it were more stereotypical (a model train set for example) would you have the same gut reaction to go "you don't have to be autistic to enjoy making model trains buddy"? Plenty of demographics enjoy a family/neigborhood barbecue, does that remove the cultural significance of the black cookout? Do you patronizingly comment that everybody likes cookouts?

I genuinely don't get the impetus for neurotypical people to hop in the comments of neurodivergent people posting about the intersections of neurodivergence and joy to just go "well makes plenty of people happy, what does that have to do with neurodivergence???" Like, do y'all just think if a neurodivergent person isn't talking about the ways their brain doesn't work "right", then they have no right to talk about something and how it relates to their condition? Just kidding, y'all complain about and diminish that too

This is how I feel whenever I see a post from autism comms.

It's just like: [normal ass thing] + teehee autism amirite guys?

But you see, normal adults don't just do fun things that aren't on the pre-approved adult appropriate list of activities. /s
