In fact - it isn't racism, according to the link you have provided.
"Racism is the belief in the superiority of one race over another."
Superiority is a key word here. The link actually ends up on the page for supremacism:
"Supremacism is an ideology which holds that a certain class of people is superior to others, and that they should dominate, control, and subjugate others, or are entitled to do so."
It’s not discriminatory, but racism is a belief not always an action. https://en.m.wikipedia.org/wiki/Racism
