I've had a quick read of some of those stories, and I agree they're awful, but on the other hand, every adult "child" that I know will at some point rant about their parents and how they did things, and the choices they made for their children.
Some consider their childhoods abusive, but this is not exclusive to having parents with ASD.
For my own part, I'm sure that at some point my children will pick out the negative parts to the exclusion of the positive. The danger of writing down an account (like in that website) is that it is there as a permanent reindeer, and because there is nothing positive written, it's easy to see the whole thing as bad, when for most people there is good and bad mixed.
It was uncomfortable reading though.
I have started to be open with my dc, and I also rely a lot on dh to make decisions and tell me what's happening (he is better at negotiating with the older dc about going out and being independent, so works it all out and helps me write a list). Without this, I could easily be controlling and far too harsh with them.
I suppose it's a balancing act, identifying the areas where his could be a problem and working out a solution.
With dd, she is getting the hang of writing things down so I can read her plans, rather than coming to me and talking loudly and quickly (does anyone remember that program Blossom? - that's dd!), when she does that I can't hear what she's saying and I get cross, which is unfair of me.
Plenty of places see anyone who is different as deranged monsters, but I think that just highlights how far the world has to go to be fully accepting of everyone.
