You don't know enough about the BBC either. They are not simply brainwashed. They have an agenda and it is not just to print and broadcast the news they think people want.
Of course they are brainwashed. No more or less than the rest of the world which is not "allowed" to view revisionist arguments.
No news organisation is totally devoid of agendas, and the BBC is most frequently accused of having a liberal one. Note that Zionist supporters detest the BBC, which they think is run by pro-Palestinians.
I'm not aware where I put credibility in Hilberg. I said I respected him for opposing the Holocaust Industry: a totally separate point. I haven't read Hilberg, but I have read Graf's Giant with feet of Clay, twice.
If you are interested in constructive debate, so am I, but I'm not interested in confrontational ad hominem argument. And let's not go even further OT.
