I do not think it would be good for them to be shot.
However, as mass shooting after mass shooting, tragedy after tragedy, has failed to move the gun-idolaters, I wonder if a different sort of incident might open their eyes. You see, they never see themselves as being a possible perpetrator or victim of these shootings. Despite the fact that so many of these shooters have similar manifestos and mindsets to gun-idolaters, they always imagine that they are different by more than just degree. They fail to see how their activities and culture give rise to these shootings. They also never see themselves as possible victims, because they always imagine themselves as the hero in any hypothetical incidents, ignoring the fact that armed 'good guys' often get killed in shoot outs.
If, through their own actions, they bring about a situation where they shoot one another, it might be illuminating to the survivors, at least. While I dislike seeing people shot, and I definitely would forbid guns at the convention were I in the position to do so, I don't think that saying 'let people receive the fruits of their own actions' is the same as 'it would be great if these people were shot.' Gun idolaters subscribe to the belief that political violence is acceptable; as a common refrain of theirs is that they are armed against the government. We have seen extra political violence in this election-unprecedented in modern times. Why not wish that violent people inflict the violence on each other, rather than on the innocent? Anyone who would carry a weapon to a political meeting is in effect advocating political violence. Why should violence not befall them? "He that lives by the sword shall die by the sword."
If it were in my power, I would simply disarm them, not shoot them. However, the choice is not mine, but theirs. If they would rather shoot one another, so be it.
We are seeing in this election the Republican Party reaping what it has for so long sown. The gun movement has long tacitly encouraged racial and political violence. The fact that their party is now divided against itself means that the very things it has used against others they are now using against each other. Is this not just? You may not like it, because you aren't used to it, and you sanctimoniously blame us for what we are NOT doing, but that your people are doing. All we are doing are standing by and letting you do what you will do. We have long lived in fear of the gun-idolaters. How many times have they threatened us? How often have I had to worry that some aggressive person I met going about my business might be armed? How often have I scanned the rooftops while I walk down the streets? And I have been more fortunate than many.
Conservatives have always been for freedom for themselves; including the freedom to intimidate and threaten others. Now they are quarreling, and instead of threatening people who respond with calls for calm and reason, they are being met threat for threat, opening the door for serious escalation. And somehow, that is our fault. It is very typical of conservatives to blame the negative consequences of their own choices on others. You are all for personal responsibilty when it suits you.
