Sex is indeed real. What these people don't seem to understand is that possessing a penis and a pair of testicles, or even once having possessed a penis and a pair of testicles, makes you instantly much more powerful and dangerous to anyone who has never had a penis and a pair of testicles.
If only opinion-formers were to read J K Rowling's views, and those of the Daily Mail, more. Then they'd realise just how massively and unfairly powerful having a penis and a pair of bollocks can make a person.
I think we should all burst into tears more often to make the point.
