First off, not to sound rude but I'd suggest you do some research and come up with opinions on your own and not just listen to people on Facebook or on the gun board. Look up statistics and studies done on both sides of the argument and then come to a conclusion based on your findings. Here's a tip: the best way to win an argument is to know more about the other person's stance than they do. For example: if you believe gun control is bad, don't just read up on information from other people who think it is bad. Read info from people who are pro-gun control, find holes in their argument, and then debunk it that way. I hate listening to arguments where people know a great deal about their own opinion but have no clue how to refute what the other person is saying so its a completely redundant argument. Just like people who don't like Obama but know nothing about him, his life, his ideologies, etc. so they just spout off about nonsense. I myself dislike Obama but I've read both of his autobiographies, listen to his speeches, etc. that way I can make a rational argument against him, not just say "oh he's a Muslim that wasn't born in America so I hate him."
Secondly, if that guy was serious about his Glock, I do applaud him for taking safety precautions, but that fact that he obviously has no clue how his gun works scares me because he's either very dumb or just doesn't know how to operate a firearm. Either way he probably shouldn't own a gun.
Well, appreciate the sentiment. My main reason for asking the question was that I am fully aware I don't know everything, so when in doubt, I ask.
