I used to say all lives matter because all lives do matter
I feel like that is something that a racist person would say, but do you agree that black lives matter?
No, i dont care about them
It is important to not be discriminatory with your beliefs. You should respect all people equally.
Cops are pigs and i hate them
You're discriminating against blacks and now you're discriminating against cops, which is very problematic of you to do. Equality and fairness should be our society's goal, and you are obstructing that goal if you continue to discriminate people of various race and occupations.
