If you want to know what Gun Control the ACLU does support...

You can find it here.

As oddball of Guns Cars Tech says: "They're for AWBs, capacity limits, "red flag" laws, universal checks, smart guns, requiring FOIDs that require you to pass a test..."

And yes that was written by their "Deputy Legal Director and Director of Center for Liberty"

Center for Liberty eh?

Said.... they're for red flag laws?  Didn't yesterdays article use the existence of red flag laws to say "see!  A Lack of gun control is why Civil Liberties are endangered"?

Why yes they did!

Their position paper does try to parse which gun control laws might be problematic, and which are okay,  though the analysis isn't exactly... deep.

Many of the options now being considered raise no civil liberties concerns. That includes bans on assault weapons, high-capacity magazines, and bump stocks. Raising the minimum age for all gun ownership to 21, currently the legal age for purchasing a handgun, also raises no civil liberties issues, as research on brain development shows that young people’s impulse control differs from that of adults.

Oh!  Glad to know it's that easy!

And yes it is that easy.

First are laws that regulate or restrict particular types of guns or ammunition, regardless of the purchaser. These sorts of regulations generally raise few, if any, civil liberties issues. Second are proposals that regulate how people acquire guns, again regardless of the identity of the purchaser. These sorts of regulations may raise due process and privacy concerns, but can, if carefully crafted, respect civil liberties. Third are measures that restrict categories of purchasers — such as immigrants or people with mental disabilities — from owning or buying a gun. These sorts of provisions too often are not evidence-based, reinforce negative stereotypes, and raise significant equal protection, due process, and privacy issues.

From earlier in the article, emphasis added.
In other words.  The ACLU is pretty okay with any gun ban as long the ban applies to everyone, and they can be convinced that any hurdles to buy a gun are fine as long as they apply to everyone as well.  But when some people are specifically blocked?  Then they'll have a problem.

Thus they see no Civil Liberties issue if all immigrants and citizens were banned from owning X,  but if just immigrants were bared from X  then there'd be a problem.

Okay,  Kind of odd they don't take a stance against May Issue.  Given that it empowers the police to pick and chose who can and cannot carry guns.

So, yes the ACLU hasn't been pro gun rights.  But yesterday's piece was particularly laughable in how they tried to justify their position.
