Certainly there are different levels of anti-gunners on the left. However the activists doing the most shouting have an ultimate goal of banning guns outright. They have merely abandoned the all or nothing approach and are instead attempting incremental measures. However the goal is the same
That is simply not true. The NRA for instance is simply for enforcing existing laws that in fact do help keep guns out of the hands of sexual predators, sociopaths, terrorists, and the like. The NRA also seeks tougher punishment for those criminals who break those laws. One example is the laws that require law enforcement and mental health professionals to report the names of the mentally ill to the national database used for instant background checks. If this law was enforced, several of the mass shooters would not have been able to buy guns legally.......as they in fact did. It is in fact the left wing trial attorney lobby that is ensuring easy access of guns to the felons and other groups that you mentioned. For instance there used to be a "Use a gun in the commission of a crime and go to prison" law. The leftwing trial attorney lobby and liberal judges somehow managed to do away with that law.It's the gun-rights lobby that is ensuring the ease of access to guns by sexual predators, ex-felons, sociopaths, terrorists, and the like.
Obviously you are not representative of the majority of gun control advocates on the left. They go much further then you claim.The measures we want do NOT restrict the ability of law-abiding gun owners to own (almost) any gun they want or how many guns they want. The measures we want are for keeping them out the hands of those who should never have them to begin with.
