It's well established that the ACLU refuses to defend the individual civil right to armed self defense.
Not to mention that orgs like the NRA have many times more funding than the ACLU and dedicate every action to that one issue.
Or the fact that you're dealing with a organization that has been one of the biggest and best defenders of oppressed groups in recent history and you're cranky that they're not gonna help you own a handgun like most of congress is.
You asked for a cite, I linked you one. That's it.
Please take this in the manner it was intended: Avoiding an unnecessary argument.
If an organization that was instrumental in protecting your right to a fair and speedy trial, was against opposed to the idea of free speech, I would still condemn that org for holding that specific position, while still recognizing that they have done good in other areas.
