On that we are agreed, ProfessorMoody. Perhaps we're talking of different platforms because in your first example, FB bigots, I wouldn't trouble to defend them, I wouldn't even be reading them as I don't post there.
Mumsnet is different and you've said that yourself so it seems like we're violently agreeing (almost). Threads like this are also (imo) fair game to comment on SPaG on as most of the posters posting invite comments freely. There's only one or two posters on this thread who've popped on to complain and in fairness to everybody, they've been left alone.
So, ProfMoody, I'm sorry that I was rude to you. We're talking about different areas and about posters on Mumsnet, we're aligned.
However, nakedscientist you're starting to get on my nerves. I'm not defending OP or any poster being called up on their SPaG for bullying, and it's posters like you who use that word unnecessarily. I don't want to keep engaging with you on this because you'll just keep accusing me of it whilst maintaining that 'this is a chatboard and therefore... yada yada', for yourself. No, it doesn't work like that.
I have more respect for ProfessorMoody in challenging what I said so let's leave it there please.
