When Steve King declared that white supremacy is just fine with him, observing that that is a racist statement is not a despicable slur.

it's a fact.

Racism: Declaring the one race is superior to another race.

Hard to get any clearer than that.

David Duke, who endorsed Trump, and whose endorsement Trump accepted whole heartedly, is happy to acknowledge that he believes Jews are inferior to Christians (that's anti semitism, a fact, not a slur), and he also is happy to acknowledge he thinks blacks are inferior to whites.

Saying that's racist is a fact, not a judgment.

When Trump and his father refused to rent apartments to black people, that by definition is racist - making life harder for people because they belong to a particular race - that's the very essence of racism.

And finally, to get back to your comment, if someone IS a pedophile (ie Trump, fondling underage girls at the Ms. Teen America pageant) it's not a slur, it's a fact.
