Thanks for your concern Destination! Rather amazed that anyone would want to hear more from me 
I did leave for a while as I was concerned I was being branded with the 'homophobic' brush which I'm not. I'm not going to repeat my non-homophobic credentials but anyone can read my previous posts.
But then Lenin seemed to suggest that free speech should be restricted on MN because it is purely a place for parents, including lesbian parents to find support.
Well, playing devil's advocate here, it's also a place for religious parents. What if a poster genuinely yet respectfully believes that homosexuality is not compatible with the religion they're raising they're children in? Shouldn't they also be able to post here?

I HATE Royal Mail.
AIBU to wonder what IPOAT stands for?
There are also sections on General Health, Pets, Politics, Weight Loss. So it's not just about parenting.
Free speech will sometimes be messy and ALL of us will sometimes be offended by someone else's opinion. But it's better than the alternative.
And Coalition - re your point on state schools, would you therefore offer no objection if Section 28 was brought back into private schools? No, I didn't think so.
