Ignoring actual disagreement about what the 2nd amendment means and what policy should be, why would the ACLU invest in 2nd amendment rights in a world where there is already a a strong lobby dedicated to them.
That "strong" lobby is dangerously corrupt and currently bleeding membership because of it. They've also turned themselves into a form of religion and not capable of being a rational actor.
Please let’s not rehash that 2008 Heller and 2010 McDonald have settled that 2A has absolutely always been an individual right - even if you don’t like that outcome.
But apparently trying to hide a fact might make it change!
