I honestly don't think we are far off it either here to be honest.
I mean there is certainly a move further away from discussion, debate, talking and listening, agreeing to disagree, conceding a point. It appears that supporters of the left and right, however you define those, is more and more heading towards I am right, you are wrong, regardless of the argument put up. When it starts deteriorating in to a shouting match "I'm saying my point louder than you are so I'm right" or if I repeat it enough you'll accept I'm right, name calling and insults, or it gets to pushing and shoving, or taking signs, flags, etc (as we have seen in protests and counter protest recently) or as we have seen here in this instance, real violence where someone gets injured or killed - you have to ask yourself if you actually have the right view, I mean if you can't counter someone's argument or at least meet it, shouldn't you have a think about that rather than resort to one or more of the above? I'm not perfect in this regard either by the way, but I've also never agreed on 100% of things with anyone I have meet. I was once told if you do, you are either naive, brain washed or someone is trying to sell you something.
I am glad we have reasonably tight gun laws and controls in this country. If anything they probably should be tighter.
