@tinfoilfedora, when people talk about taking away guns, I always say "Lets look at a demographic that contrasts with the demographic that was murdered en mass---Lets compare the unarmed night clubber demographic, or unarmed school children. Now lets compare how many mass killings they have endured with that of bikers at biker bars---I am unaware of a single mass killing terrorist event against this demographic."
Then I ask them "what is the big difference between these demographics? the night clubbers and children are unarmed and forced to spend their time in establishments that do not allow honest, upstanding citizens to enter while armed."

And even then...they generally don't get it.
