It's a really difficult debate to have with a lot of people, though, and I can appreciate that people will have very different views on it.
If we see autism as a terrible disease, then we're asking the public to be horrified, to shy away from contact with us, to treat us as if it may be catching. The social isolation we already endure gets worse, the quality of life for us gets worse. I know what it's like to meet someone who thinks that this is a dangerous disease of some kind - they invariably treat me like (fill in the rude word of your choice). It's absolutely awful
It doesn't mean we have to accept absolutely any behaviour from those on the Spectrum though. If a child is doing something very disruptive and destructive, it's often a cry for help, often from some sensory input that is totally overwhelming. Helping us to lead a life that's tolerable and enjoyable is great. But I worry a lot about these people that offer to 'cure' a child for a bargain price of tens of thousands of pounds etc. There simply isn't enough evidence to say it actually works any better than cost-free things the parent could try themselves. Note I'm not saying "there is no evidence any of this can possibly work". There's some, but not enough.
I don't buy the emotional blackmail stuff from some of the cure-peddlers about "if you loved your child enough, you'd do this for them' either. If we don't know the full effects, some of these families could be doing a great deal of harm to that child without even realising it.
I had a conversation with a parent who explained to me that their ASD child went absolutely wild when they took them unexpectedly to a noisy social event last thing in the evening when they were tired. They said this showed how important it was to cure autism, to stop this child from going wild. Er, well, if you take a child with an ASD unexpectedly to a noisy social event when they're exhausted, who'd be surprised that they go wild? The parent caused it. Yes, the child will scream and fight as surely as if that same parent said "Gosh, I pushed my child down the stairs and they screamed - so it's clear that we must stop them screaming and thrashing about by giving them therapies so they learn not to make a fuss any more"
Sensible tested therapies approved by the NAS etc, good training, low-stress environments, love and respect, consistency - those are all definitely valuable for a lot of us.
