CK I think you could make a strong argument in court that the clause you quoted above is specific to and limited to the context of the SDA, meaning carrying outside the home. The SDA in no way affects anything whatsoever in regards to in-home carry or use of firearms.
As far as I can tell.
You could be in for a fight, though.
All likely true, but with the new open carry law, it is linked to having a concealed carry permit, thus linked to SDA. However, with that part of the law specifying that "ANY" homeowner can open carry on their own property without a permit, I'd think that one would be safe.
