I do love how they defend him in part by saying he killed a convicted sex offender as if he could have possibly known that and as if that were his (or anyone's) job to do.

That's because for Conservatives you're allowed to take lives to protect property. You are not allowed to damage property to protect lives.

Really shows where their values are.

You don't understand:
A white woman can have a black baby.
A black woman cannot have a white baby.

This is very normal and makes perfect sense. Stop looking at it closely.

There's the "One Drop rule." (Wikipedia)

"The one-drop rule was a legal principle of racial classification that was prominent in the 20th-century United States. It asserted that any person with even one ancestor of black ancestry ("one drop" of "black blood")[1][2] is considered black (Negro or colored in historical terms). It is an example of hypodescent, the automatic assignment of children of a mixed union between different socioeconomic or ethnic groups to the group with the lower status, regardless of proportion of ancestry in different groups.[3]

This concept became codified into the law of some U.S. states in the early 20th century.[4] It was associated with the principle of "invisible blackness"[5] that developed after the long history of racial interaction in the South, which had included the hardening of slavery as a racial caste system and later segregation. Before the rule was outlawed by the Supreme Court in the Loving v. Virginia decision of 1967, it was used to prevent interracial marriages and in general to deny rights and equal opportunities and uphold white supremacy."
