It's the Infantilizing that Annoys Me the Most
I also use the term "mothering."
It's where I get these little lectures from people who are allegedly friends or acquaintances, and they speak to me like I'm a child who broke a rule at recess (I'm 53 years old). To quote an autistic comedian, "It's not that I don't understand the rule. It's that I think your rule is Bull S---."
Also, in most cases, the rule only applies to me. Like, if I use the F word, I get told, "Hey, there's children around here," but then notice the same exact phrase being spoken multiple times by a variety of other people in the same context, sometimes within a minute after getting lectured.
I should add here that my special brand of autism is similar to a lot of educational creators on youtube. I work in communications for an engineering company, so I am actually extremely good at understanding how people communicate, different perspectives, racism, sexism, professionalism, etc, etc. Like I'm literally the guy who sees and understands conflict between people on a social level better than most.
But there is something about the way I present myself to people that makes maybe 5% of them think, "This person doesn't get it and it's my job to treat him like a child in front of everyone."
The only solutions I can think of are to either identify these people and either be very careful about what I say in front of them, or avoid them altogether. Or, mask really hard around them so I give off the, "It's not cool to treat me like a child in front of everyone" vibe.
Anyway, it is frustrating and annoying.
Edit to add: I use a phrase "The Group Gilligan." Gilligan was the lovable childlike idiot on the show Gilligan's Island. One of the running gags was that when he'd say something stupid, the skipper would hit him with his hat.
The message here is that when you give off a "Gilligan Vibe," certain people in the social group believe, "It is appropriate to treat you without respect, because that is your role in the group."
