Sooo....
You're posting on the Internet, where speech is probably freer than it has been at any time in human history.
Furthermore, you're on Mumsnet, one of the least censored, filtered or moderated sites around.
...who exactly do you think is denying you free speech?
If it's the case that you've posted something and a lot of people disagree with you, you might want to consider two options:
a) you need to argue your point better, or;
b) you are, in fact, wrong.
it's surprising how many people dismiss b) out of hand , so if you're unwilling or unable to go for a), and it upsets you to be disagreed with, maybe you should find a site where people do agree with you?
(and can I just mention that your last post just attempts to insult animula, without addressing any of her points. Want to re-read your OP and reflect on the irony?)
