I can't possibly argue with you if you don't understand what racism is. so lets start there, look up racism. like define racism. seriously. because you 1st at least need to understand what racism is, and to differentiate from racial prejudice. I know you think you know, which makes it hard to learn something. but theres no point arguing with you unless we're talking about the same thing.
To help, here is what i'm talking about (and media and academics, people who study racism and its effects, victims of racism, pretty much everyone except white dudes) when i talk about racism
racism is a system of OPPRESSION based on race. you cannot be opressed if you are the opressor. thus WHITE PEOPLE IN THIS COUNTRY CANNOT BE VICTIMS OF RACISM. it's simply not real. racism has for centuries established and upheld heirarchies based on race which benefit white people and oppress black, indiginous and people of color. this is history. centuries of history and still ongoing -
Certainly there are instances of racial prejudice against all races. but you're not opressed by it in any meaningful way. Social, systemic and institutional racism only benefit white folks.
If you can think of the handful of time's you've gone to maybe a predominantly balck neighborhood and felt unwelcome, or someone made fun of your embarrassing white people dance moves, good. focus on how shitty that was, and recognize your privelege. for beign able to identify a few select instances. now imagine it wasnt that one or 2 times, it was always. and it affects how you're treated by police, by teachers, by employers. THAT is racism.
so when i call you a racist, it is because you support and defend that system, you defend that inequality by pretending it isn't real. and thus by supporting a racist system, you are racist. simple as that.
I don't make this up. this is well accepted academic definition of racism, i am very consistent in my definition of it, as i am of the difference between racism and racial prejudice, but be sure - your defense and denial of the racism inherent in our system makes you, intentionally or not, racist.
