True Left

There are not just laws against mere "denial", but there are also laws mandating that the sacred narrative is taught:

As of April of 2021, laws mandating education about the Holocaust were on the books in Austria, France, Germany, Hungary, Israel, the Netherlands, Poland, Switzerland, and the United Kingdom, as well as in the U.S. states of Arkansas, California, Colorado, Connecticut, Delaware, Florida, Illinois, Kentucky, Michigan, New Hampshire, New Jersey, New York, Oregon, Pennsylvania, Rhode Island and Texas. In total, 16 states have mandatory Holocaust education.[1]

I doubt that the teaching of the ethnic cleansing of Native Americans, US concentration camps for American citizens of Japanese heritage during WWII, etc. are mandated by law in most of those US states!!!
