Conservative claims of bias would have more weight if these weren't the same people that aggressively legislated and criminalized being employed while black, LGBT, and/or women. I don't accept "that was the past" deferrals either as that was not very far in the past, such claims seem to presume that all the legal barriers that were being so aggressively protected were suddenly dropped completely when the SC rule segregation was unconstitutional.
