But you can't use anecdotal evidence to create a scientific theory. So no matter how many people said, "Hey, I'm autistic and I have synesthesia," you would still need to gather a random group of auties, gather a group of random NTs, test for synesthesia, and see if the auties had significantly higher levels of synesthesia.
But you can point to anecdotal evidence and say "autistic people do seem to talk a lot about synesthesia." The only place I've seen more talk about synesthesia than this forum was an actual synesthesia forum. Anecdotal evidence
is evidence, after all. Many studies involve collecting anecdotes from a lot of people and turning them into statistics. For example, studies about how many autistic children are bullied are based on anecdotal evidence and self-report, but this does not make them invalid.
And, really, you can use anecdotal evidence as the starting point of a theory. You just need to follow it up with testing, analysis, and empirical data.

I think it's fine to say, "Yeah, they've been talking about it for years, but we didn't have scientific proof until now." What's not fine is when the scientists who know how to properly test a hypothesis are sitting in their labs and not even thinking of talking to some autistics to see what ideas their discussions of autism spark. They're giving up a huge opportunity when they don't talk to autistics about autism--they miss our perspective, they don't see what's important to us.
And this is why Simon Baron-Cohen said he didn't think there was any connection,
despite the fact that more autistic people having synesthesia is pretty common knowledge at least in online autistic communities (like this forum).

So, yeah, we need proper science, and you can't do that just chatting on an internet forum. But if you try to do proper science to study a group of people, without actually talking to the people in that group, then you aren't doing proper science.
There's a huge difference between "using a forum to do proper science"* and SBC stating that he assumed that one had nothing to do with the other despite the fact that there has been a persistent connection between the two in intra-community discussions among autistic people. Which is why I criticized his statements - because he doesn't seem to acknowledge what autistic people talk about as valid. So
even though synesthesia is something autistics experience, and report experiencing at a relatively high rate,that is not even relevant to SBC until he decides to do the research himself. There is something fundamentally wrong with his approach to autistic people when he basically ignores us and relies strictly on his own observations.
* Although you can practice science via a forum, as science is a procedure - the scientific method - which can be used to test most anything one might care to test
