Yeah? As a Christian, I have no compunction whatsoever in shooting back.
But Christians will not be persecuted by violence here in the US. There will be no shooting one way or the other. The persecution will instead be by legal means, and will increase slowly over time.
And it's already started. Consider the Christian bakers who refused to bake a cake for gays. Eventually folks who speak out will be charged with hate crimes.
It's not that everyone in the US is armed to the teeth, the major difference is all Americans have tremendous access to:
1. Technology such as live cams, GIS data, search engines. Americans can find anything, anyone, everyone in minutes. Not enough time for anyone to run and hide anywhere.
2. Transportation. We will come to you in swarm droves.
3. Pissed off Americans will level everything and everyone including everyone you've ever been related to or ever known, whether guilty or innocent of anything.
Just stay away and leave this wasps nest alone.
