I've read and even said a lot of uncomfortable things on the internet, but seeing someone lament the loss of not pitting a holocaust survivor with a denier probably takes the cake.
A lot of holocaust survivors have made very cogent cases against deniers, you may be underestimating their strength. Maybe some people couldn't do that, but other people could. It is a lot of people we are talking about.
Hoisting someone up to get humiliated on national TV is giving them equal credence? It's impossible to give equal credence to Flat-Earth equivalents, except by engineering things so that they get to talk about their "persecution" without saying anything about what they believe. (That is a common trick, watch out for it and you'll see it in many fringe subcultures.) Get them talking about their beliefs on a concrete level and the credence goes out the window. Putting its head on a stake where everyone can see it will do nothing to assist it.
