We are required to believe that it happened, because it did happen. I believe that anyone with any authority such as a school teacher, or anyone who tries to convince others that it never happened, should at least be fined a large monetary amount. Spreading false information should always a chargeable offence.
The government forcing us to believe that same sex marriage is a human right, is ludicrous and wrong. The majority of us don't believe in same sex marriage and never will, no matter what the government tells. The government should never be allowed to tell us what to believe in when it comes to personal business. But the government is right about forcing us to believe in the Holocaust, because it is based on true fact. Same sex marriage on the other hand, is based on personal feelings, opinions and religion. We should never be forced to accept sex marriage as law.
