> Should the ACLU defend the rights of someone to blow up nuclear bombs in their backyard?
If someone actually went to court over this, I would hope/expect that the NRA would send some lawyers. The ACLU isn't that into the second amendment and has never been. However, nobody has gone to court over this. They did go to court over vaccine mandates.
By the way, the only grounds the government would have to stand on here are radiation-related. It is broadly legal to use explosives on your own property unless you're too close to someone else's property. It is also broadly legal to build your own weapons.
