Vortex works great. In general, you'll want to use some kind of mod manager and in the Skyrim realm, the main alternative to Vortex is Mod Organizer 2. I have heard that there are some exceptionally fiddly setups for which Mod Organizer is the better choice, but Vortex is a very good one. Much better than the old Nexus Mod Manager.
Installing them yourself is basically irreversible, and things can get complicated if you don't have a mod manager keeping track of stuff.
All they have to do is, instead of calling it a "law", call it "militia regulation" instead. "Militia" is the entire arms bearing populace; if you own a gun, you are, by definition, part of the Militia. And the 2nd amendment doesn't merely say "everyone has a gun"; it does so in context of maintaining a "well regulated militia". All the right to "keep and bear arms" does is prevent them from requiring we store our arms in a central armory (which was one of the controversies over the matter in England when the right was in development).
I would say we also have a right to own a car. That doesn't prevent them from requiring we maintain the capacity to bear responsibility if we should accidentally exercise that right improperly.
