May I generalise?
Well, theres's this Disability Discrimination Act, which is a law, that says that service providers including UK based websites, even free ones, have to make reasonable efforts to include us, rather than us have to leave.
It works like this, just for our reference:
Person A identifies that they have a disability and is, if necessary, able to prove the diagnosis. This is important.
Person B says something that causes Person A distress because of their disability, e.g. is rude about the disability, mocks it, spreads hatred about it or its characteristics in a malicious way rather than a way that is intended to get help and support for a genuine situation.
Person A explains their distress and how it makes them feel as a person with this disability.
If Person B actually apologises or rephrases or whatever else that solves the situation there and then, brilliant. That will solve about 99% of situations straight away.
If person B instead says (in effect) "Couldn't give a fig what happens to you, why should I have to take any notice of you, I have my right to express any opinion I like - I have to tread carefully round people at home and I don't want to do it here", then it may become a situation where Person A cannot reasonably access the service. Why? Because they are being put into a hostile or intimidating situation for that disability.
The service provider has to provide 'reasonable access', so if they are made aware of the problem, they need to seek to solve it in some reasonable way. Or there's anything up to a £30,000 fine for the company. The individual, if continuing to deliberately pursue someone with a disability in a harassing way, could also face police charges, and those charges would take the disability into account when upgrading it to an Aggravated Offence. It's actually all quite serious stuff. Not easy to get the courts or police to pay attention, but that's what the underlying laws say about service provision. It's the sort of advice I help organisations with.
So, no, it wouldn't be fair for either me or anyone else to have to leave mumsnet. And any sensible debate is absolutely fine. So is asking for support. So is expressing dismay or distress about a personal situation.
But if a person with a disability is asked to leave a service or forced to leave a service by the service provider because of their disability or behaviour caused by that disability, then that becomes a very illegal thing indeed (unless they are a danger to others).
Remember, this is all just me trying to answer the question of why I don't just leave mumsnet, not me threatening anything. I provide advice and information.
We would need to find a workable solution instead, which is what I'm trying to do.
