Now, after getting loaded by right-wing whack-jobs by the Trump regime, the anti-gun zealots might as well give up for a bit. It's a completely lost cause, as is the abortion debate. All that energy and angst would be far better spent trying to convince people to stop voting Republican.
In principle I agree with you. However, by drawing attention to these kinds of rulings, I do wonder if some of the thinking is that while accepting that it is a lost cause currently, it may change the minds of more moderate republican voters to see what is being done in their name and encourage them to reconsider?
Maybe just wishful thinking.
