It's just very hard for me to understand how this issue (or others like abortion) would be above all others. You are voting for a government with a tremendous amount of power and responsibility (military and defense, infrastructure, running a huge economy, world trade, healthcare, etc). I just can't imagine voting based on a single issue like the 2nd amendment while ignoring all the others.
I respect your opinion, and I know you are not alone. It's just hard for me to understand it, that's all.
