my grandma is racist

how do I say this

evidence 1:

so like, one time my grandma saw an Indian Woman and my grandma told me “look, it’s a black person!” and I said “so what” and this bitch goes “they’re different from us!”

evidence 2:

I was in the car with my grandmama coming back from an old friend’s house and she asks me “what culture is your friend from?” so I told her and she looks at my grandpa and says “so her friend isn’t black…”

evidence 3:

she asked me if we had black people in my school (Australia is multicultural) and tried to say “black people” in english as if I don’t know how to speak Chinese

evidence 4:

she saw an African (I think) on the road and she said to me “that black person is so fat, be careful of those kinds of people. they’re dangerous” that girl was skinnier than my grandma…

bonus!

my grandma doesn’t like gays and shit because they can’t have children (she wants me to have a child like no)
