Yes, it does mean you’re undecided, but worse yet, your wording tells me you haven’t even been made aware of what you should decide about in the first place. The issues you’ve raised have been contrasted as if dichotomies, when that’s not even close to true. It’s good that you agree abortions are the choice of the mother, as that’s the bare minimum we should expect of a rational human being who’s not evil. Then you immediately contrast it by asserting you haven’t even thought about your own morality yet – what does “unrestricted civilian gun ownership” even mean? Could I roll up to your front yard in a Panzer? Maybe you’d invite me in for some coffee as I hold a glock made of pure Uranium? Besides that, “anti illegal immigration” is a largely meaningless statement – everyone is, even “illegal immigrants”. They’d rather have the stupid law allow them to visit legally.
Point is, the divide doesn’t lie between political parties, but between choosing to be evil and support a capitalist dystopia where money is worth more than lives, or be good.
