Gun control has been one of if not the biggest losing issue on national elections, it has even been hell for local elections in liberal states like colorado. The whole frenzy relies on a tragedy to push gun control when emotions are high and logic is low, which literally points to the fact none of the gun control advocates really could persuade the american people on any level of logic, and have to resort to emotion and hope that emotions does not end too fast to push their laws.
Because it is one of those single-issue topics that absolutely affects a person in the most real way. The government is literally trying to take away what you own - and is trying to find a way to imprison you and completely destroy the rest of your life if you don't do things exactly correctly.
Moreover, most gun owners know how extreme gun control REALLY is now. Here are a couple of examples where if you do it RIGHT it's ok - unless the regulation changes in the next minute - and if not then you go to prison for 5 years, lost everything you have, your career, banned from many types of license, bonding and even international travel - and most important you are banned from voting and owning any firearm for the rest of your life. Destroy and eliminate the gun owner:
You have an AR15 with a 10 inch barrel. What kind of buttstock is on it? They LOOK nearly identical and definitely do the same thing - exactly. But one isn't called a buttstock by the BAFT, it is called a "rifle support." So IF you have a "rifle support" - you're ok. But if you have a "buttstock" on it, that's a federal felony.
You buy a rifle, used, go thru the background check and the whole works. You're out shooting with some buddies. You all are shooting identical appearing rifles in every way - even same brand, stock, scope - literally everything. In fact, they are all out of the same manufacturer's stock
An ATF officer comes along, asks to see your rifles. One guy's rifle. Another guy's rifle. Now your rifle. The officer tells you that you are under arrest because your firearm is illegal under the "points" system. Turns out some previous owner had repaired some internal trigger parts and they were not made in the USA. That's one "point" to many against your gun/you. So away to federal prison you go - say goodbye to your kids, wife, family, job, house, car and ever voting or owning a firearm again - banned from most professions directly and indirectly.
Of course, I'm not writing anything all of you don't already know, correct? All of you get up in the morning, go the BATF website, to check to see if they changed the rules - because what is legal today they might decide is illegal tomorrow - major felony illegal.
There are NO other products like that of any kind in the USA. The government does not just change a regulation is some agency memorandum, and everyone owning a Prius is a federal criminal to be imprisoned - and banned from every owning or driving any kind of vehicle again, nor voting. Don't Prius owners and you are in a position of power in government? By tomorrow you could turn everyone of them into a federal felon unless they secretly destroy their Prius and hide the scrape.
THIS is why ANY talk of MORE gun control is a single issue to MANY people. The goal of gun control is to be able to send gun owners to prison, to destroy their lives, to eliminate them having any political relevance and - of course - assure they never have a firearm again.
