I actually think that tabooing those topics and refusing to even discuss them makes them a lot more powerful than they deserve to be.

If a topic is not discussed in public space enough, its counterpoints and refute arguments become less and less obvious and visible, which leads to people colliding with it for the first time not being mentally equipped to muster rational arguments against it out of their own brain due to not being mentally equipped or mature enough. Not everyone can recreate a hundreds of years of mental and cultural progress on the spot without any external references and talking points readily available.

So if you know nothing about holocaust and encounter a convincing-looking argument that it's a hoax, it's very easy to adhere to this idea and move on with your life thinking it's the truth, especially if you don't see any moral issues with it.

Tabooing controversial topics creates an ideological vacuum that is very easily gets filled with garbage. Especially if the the only actors willing to break the taboo are those who have questionable motives and pushing some sort of angle.
