Holocaust 23,800,000 results.
Armenian genocie 1,260,000 results
Urkranian genocide 1,310,000 results.
The answer is Illegal for an Education system to teach that event as untrue. Also the system should also teach about the other less known genocides . It is in my understanding that a lot nations do not even accept that the Armenian genocide happened , which is in my opinion the same as denouncing the Holocaust as a lie.
I voted Yes though since it is within Parental rights to teach what they believe is truthful mainly because we can't control what they teach their children and it will be a fascist thing to do.
