You’d have to be willfully ignorant to believe that widespread civilian gun ownership DOESN’T deter tyranny.
I always laugh when gun grabbers say “what could you and your ARs do against a modern, mechanized army?” I think just about anyone who spent any length of time in Iraq or Afghanistan could answer that question. An armed populace may not be able to defeat a conventional army in the field, but it can certainly make it costly and unpleasant for that army to occupy territory. Imagine Fallujah or Sadr City with 10 times the guns available to the insurgents.
Republicans buy guns for protection while Democrats buy them to commit crimes.
The majority of the armed services are real Americans. They will not fight to kill their fellow Americans against a government hell bent on destroying the constitution and its citizenry. That is one thing all liberals seam to forget.
