Based on the kinds of things I see people posting on social media, I think the attitude regarding amendment #2 stems from fear. Guns make them feel safe. Including feeling safe from the government who they fear will come to try to do things like silence them and destroy their ways of thinking or even cause physical harm. So it causes real conflict for them when the government wants to put limits on guns.

On top of that, the 2nd amendment itself is about defending against the government. It says that armed citizens are necessary to be able to form a well-regulated militia. The founding fathers had just broken free of an oppressive government, so they wanted to be sure it was possible for states to break free again if necessary.
