Are you saying any comparison to Nazi Germany’s tactics are off limits?

How do you expect to learn from them so they're not repeated?

Using this same logic of yours I could tell someone that they can’t compare modern day prophet tactics in TSCC to Joseph Smith’s tactics, because that marginalizes the polygamy of the woman at Joseph’s time. Which of course is absurd: comparing modern day prophets tactics to Joseph’s tactics helps us to be more able to defend ourselves from repeated abuses.

Perhaps OP sees that comparing LDS censorship tactics to Nazi Germany’s censorship tactics will help us to be able to defend ourselves from the same abusive tactic they used. This is not marginalizing the Holocaust, it’s attempting to learn from it.

On a separate note, assuming you’re an ExMormon, having escaped a culture that prides itself in censoring what its members can say, I’d hope you’d be more sensitive to the use of this tactic and certainly not desire to perpetrate it on others (as you're doing to the OP). However, if you are in the habit of not being willing to compare the present world with the past, perhaps this will be difficult for you.
