What you said above could be applied to both sides of this debate, even in this thread. I hope that was your point, and not just an irony.
Not really.
One side says "there is no way to accurately tell exactly how many died in the Holocaust, but it's estimated the number can go as high as 6 million".
The other side says "the 6 million number is a lie they made up to push the idea the Holocaust happened".
Let's not pretend that attacking estimates by misrepresenting them like this is an argument made in good faith.
