Oh dear. I think people are entitled to their opinions and sweeping statements come from all quarters.
I also think it's good to have a balance of opinions - I only got involved with this thread in response to the claim that it's mainly those without buggies who are creating access problems for wheelchair users - and I have witnessed otherwise. So I'm not going to let something remain unchallenged if I have seen evidence to suggest that's not a fair comment.
I have a right to an opinion as much as anyone else but I do think some people are being very selective in their quotes and getting things out of proportion. Ultimately, we all benefit from a bit of consideration from others.
