after the war, laws were made in germany and other countries, especially countries in europe, that make it illegal to say the holocaust never happened. sometimes they also ban questioning the number of people affected by it, which is saying that not so many people were killed as most people think "who wrote this?" there has been some controversy over whether this affects people's free speech. certain countries, such as germany, austria, and france, also banned the use of nazi symbols. it is also banned to make a nazi pledge position on a popular media source to stop nazis from using them.
