Yes, that's me: paranoid.
If it's 'filtering' on the basis of someone in the ABC's opinion of what's a 'fringe' issue, that's censorship.
It's OK to 'filter' defamatory and obscene material. It's not OK for a taxpayer funded broadcaster and website to decide that all questions about a particular subject matter that a group of people consider important is not deserving of publication.
But note the word "if".
