the true deffinition is believing that one race is superior to all other. Hatred without reason of another race. ETC.
SADLY today that has changed.
In todays world this is what makes you racist:
Mentioning race in any way
Not being totally politically correct
Supporting your race
Being white
Telling a racist joke
Judging by hair color
Disliking something someone likes
etc.
As you can see this word is grossly over-used and mis-used. It's truly pathetic. I pity the world. The truth is racism is ignorance and is bad. But not everything is racism and not everything has to be about race. Hope you learned something!
