I wouldn't have to be defensive because there's no amount of truth in that. So it doesn't offend me. It would be a stupid charge.
Something in what ctd says strikes a nerve. Why is that?
Perhaps it's the thinly disguised glee with which his supporters pile on, trying to evoke a reaction. Personally, after having enough exchanges with ctd, I know enough about him to know that he is inconsequential, and best ignored. He holds some ideas and beliefs that are marginal at best, and delusional at worst. His opinion doesn't matter to me, nor should my opinion of him matter to him. By your reasoning, if he objects to my assessment of him, it must mean there's some truth to what I say. If you object to what Dr. E, AJ Armitage, or anyone else says, there must be some truth to it.
Let's just drop the whole thing. Hyper-this, hyper-that...bollocks on the whole lot.
