It's happened before though, that seemingly insignificant things motivate people to do this (https://en.wikipedia.org/wiki/Hitler%27s_reference_to_the_Ar...), and specifically with the Armenians again, which is, I guess, a sort of irony:

>Our strength lies in our quickness and in our brutality; Genghis Khan has sent millions of women and children into death knowingly and with a light heart. History sees in him only the great founder of States. As to what a weak Western European civilisation asserts about me, that is of no account. I have given the command and I shall shoot everyone who utters one word of criticism, for the goal to be obtained in the war is not that of reaching certain lines but of physically demolishing the opponent. And so for the present only in the East I have put my death-head formations' in place with the command relentlessly and without compassion to send into death many women and children of Polish origin and language. Only thus we can gain the living space (lebensraum) that we need. Who after all is today speaking about the destruction of the Armenians?

The speaker of the above quoted words is Adolph Hitler.
