I think we all need to consider how helpful this is on all the levels. I would have loved to have this to see what others have learned, and what is thought when certain gear and/or people types are on the field.
i.e. I thought about getting a box mag for my m4 at one point, but I didn't after reading into the reactions it has gotten before. I also experienced it for myself when I was at a game and seeing a box mag user in action. The player had a hot gun with a box mag spitting BB's at crazy BPS. I saw the advantage and the pisses-me-off-factor for myself (and my head was bleeding).
now not everyone is going to get to learn for themselves now, which I encourage, be it by personal mistake or one made by people in the past. But this is as good way to get the things we learned, and the common stero-types out for those who don't know the search button. So why is are there these pointless arguments in the firstplace?
And no one just wants to be spoon-fed, they just want to fit in and see themselves not fail. They want the affirmation from people who know what they are doing.
