I pray there is no defense force for this on GAF
I don't know about GAF, but I've seen it defended, in two ways. First, when it's not a two-way conversation, like on a right wing TV or radio show, they just completely ignore all the obviously unfair stuff like removing early voting, polling places, etc, and just focus on voter fraud. There have been a handful of times where a GOP personality has said they were someone else and received a ballot. They use this as proof that voter fraud is rampant, jumping straight to the conclusions that this would go unnoticed, that the same person could vote multiple times, etc, none of which are proven, and none likely true.
The other defense is just a defense of the racism angle. These geniuses say these laws aren't racist because they aren't meant to hurt black people for being black, but only for being Democrats. Because that's so much better. In fact, IIRC, the John Oliver segment has a GOP member saying much the same outright, in an interview with John.
