I see a lot of people quoting this small fraction of President Roosevelt's speech which was given over a hundred years ago across the sea in France. There's another way to apply this to our own lens of perception which I wanted to share. It seems to be an almost common occurrence in groups to have "that guy". You know the one who no matter what knows all and has done all. Someone posts a question about a firearm/car/bike/war etc etc. while "that guy" responds with well you should have known better than to get a blah. While these parallels are not the same it strikes me as trying to kick the guy trying to figure it out.
I believe there's an old saying something to the effect of if you're the smartest person in the room you're in the wrong room. When someone asks for information think of it the same as if someone was asking for help. They aren't looking for your condescending remarks but instead actual information. Ill try and illustrate -
"My Chevy keeps leaking oil anyone know how to fix it?"
"PISS ON CHEVY SHOULD HAVE GOTTEN A FORD!"
As you can see while its meant in jest it doesn't actually do anything to help solve the problem. Even if your "witty" response is correct and they agree it still doesn't fix the leaking oil. I'm not much of a car guy so I see the above in regards to firearms more often than the example but you get my point. Try to be constructive in your community instead of just adding how wonderfully intelligent you are to every thread you read.
