No doubt, but that's where I said it needs to go both ways. How many times have I watched someone post in OMG WTF textspeak asking how to set up PCT when there is a sticky right there and get mad when someone points it out. If you want to be treated with courtesy(in this case show some effort at learning), you have to expect to do the work. In your references to things that have come up in the many mudslinging threads in this particular forum, adding fuel to the fire serves little. If someone says their buddy squats 800lbs at a bodyweight of 135lbs, then the onus is on them to prove it. Once you have asked/explained that, they provide it or you disregard what they have to say.
I see people who bluster and angrily provoke, but I see just as many people with these snide little remarks that add just as much fuel to the fire. But, I can also point to members that have provided years of help on here that I think every member holds in high regard. They might now agree with them on things but that doesn't change what they bring to the group.
I think one of the biggest blocks to communication is how open the written word becomes on the internet to interpretation. One of my old professors said you can always tell someone new to a discipline because they can find once sentence in a 500 page book that they feel isn't correct and then disregard the whole thing.
