Keith, let me ask you again:

Do you deny that 17 million died?

If you do, then you will be able to point to the historians whose research casts doubt on this number. Even if its David Irving.

If you do not, then your opinion is clearly that the deaths of 17 million were worthwhile in your cause. If that is your view, they you can hold it, I find it repugnant. If historians also hold that view, then I find their views repugnant also, but they are no more qualified to express an opinion than you or I. If that question is in academic realm, it is moral philosophy not history.
