"I have accepted this as the only explanation on offer.
I have no other reason to support it, but the proponents know rather more about it that you or Don!"

In other words - keith doesn't want to think about it critically, he is ignoring the points made on both sides, and this is because his elders and betters have stated an opinion.

The lack of substance to support that opinion is of no concern to keith.

They are his betters and that is enough for him to bow to their greater wisdom.


But funniest of all, he states that he doesn't know enough to have an opinion, yet he clearly knows enbough to know that his elders and betters opinion is correct.


Hipocrisy, dishonesty, and twisted nonsense. all in the name of fighting to the death in the name of a racist hypothesis.
