The most idiotic arguments come from those who think they're correct only because someone told them they were. From the gun nuts to the creationists, it's always the same arguments.
Now they whine about always hearing the same counter arguments, yet fail to acknowledge their arguments never change. It is telling of a deluded mind, or as Einstein said: the definition of insanity is doing the same thing and expecting different results.
This habit comes from the fact that these morons refuse to ever learn, either because they fear learning or they are not honest enough to accept new information. Creationists fear learning as it challenges their beliefs, should they ever hold their own claims to the same scrutiny they do for any other god they'd lose all faith.
For gun nuts it is dishonesty, to admit that they are wrong means that they must concede to lying. So they must keep their original lie by adding more lies to cover it up.
Commonly language of these two groups is identical, often they play on emotion and discourage any scrutiny of what they state. They will fire a lot of garbage claims, bullshit points, and obvious lies to overwhelm the opponent, waiting for that moment when you just give up.
The trick to combating this is by staying on topic, even repeating your original point until they address it. The longer they refuse to address that point, the more foolish they look.
Gun psychos are the least honest of all the morons, they will use confusion and fear to dissuade anyone from opposing them. Fear being their primary tactic, once you stop fearing what they claim is a danger they lose their minds.
The other term for their tactics is terrorism. Religious preachers use this tactic as well, scare people into agreeing with them in spite of having no solid evidence to support their claims.
Another terrorist tactic is to target those under the pressure of extreme grief, then use the confusion and desperation of that grief to sell a product. Whether that product is an idea or tangible, it is never a good product if sold during grief.
