Should we tolerate certain behaviours just because they are from someone who has difficulties in life? Should they get a free pass to unacceptable behaviour which is anti-social?
Absolutely not, regardless of the circumstances because these actions are having massive negative impacts on others.
Just because you are autistic doesn't mean you are incapable of managing yourself. Everyone has triggers and you have to learn to recognise them and take responsibility for your behaviour.
Yes burn outs happen but this is where it is crucial to draw lines and boundaries much earlier on in the process so you aren't getting to a point of having a full public meltdown over claiming you are female when it's fucking obvious you are male from every action and cell in your body.
Tolerating certain things and affirming them as acceptable is definitely part of the problem not the solution.
Just like even if you really really really want cake as a small child, you learn that sometimes you can't have it no matter how much you scream and you don't scream about it when you are an adult. You learn and make sensible decision and understand you can't afford cake and cake isn't good for you so you don't have a tantrum over not being able to eat it. Sometimes you may have an occasional slice of cake but you get that cake by not being a bloody twat about it.
And yes the vast majority of autistic people can manage cake buying in their life in a sensible way when it comes down to it, even if they eat cake more often than the average person. Because they can regulate and understand boundaries in normal everyday life when they are taught how to do so and understand why it is important.
This patronising idea of autistic people as overgrown bloody toddlers doesn't help anyone. Least of all autistic people themselves.
