Understanding why someone does something and the reasoning behind it , and suggesting you have no business telling people what to do is not the same as what Bob said. Any reasonable person, and even those in that thread, can understand that. Striving for understanding of something does not mean you inherit the qualities of it. Believing that you don't have a right to tell anyone how to play doesn't make me instantly supportive of the actions either. I simply think you should mind your own business and leave people alone. Those clear sellers don't prevent anyone from working on the turns. They don't stop anyone from grabbing friends, queuing up, and working on it until they get a win. If you want to down T5 so bad then people should spent less time fuming about clear sellers and more time in T5 working on it. There are not enough people in the game for clear sellers to prohibit you from completing this content. The only thing preventing people (in no specific importance or order) is some combination of lack of time, lack of dedication dedication, and finding 7 competent people to assist you.
I am a raider. You generalize actions to all raiders, therefore you mean me, all the other nice raiders I know, and more. It doesn't matter if your specific statement doesn't represent me for me to find it offensive because it targets raiders which is a group I most definitely identify with. That's no different than making a blanket racist statement and then looking over at your friend who is a member of that race and saying "sorry, I didn't mean you though bro." It's still greatly offensive. The real solution would be for you to fix your rhetoric and to stop referring to all raiders collectively. Say "Some of the more malicious raiders" instead of the collective "raiders" or something to that effect. It's not that hard to prevent yourself from being offensive to an overly large group of people that don't all represent the specific demographic you're talking about. The way you're doing it is no better than racism. Showing prejudice and disdain for an entire group of people based on the actions and behaviors from a subset of them.
Despite how ridiculously out of context that quote is, that player who said it doesn't represent all raiders. A point I've been trying to get across to you from the beginning. Pointing out any one bad player doesn't make the whole group bad just as no good player makes the whole group good. Your quote only makes your argument look more petty and short sighted.
Even despite that specific example the advice to "Make more friends" and "become a member of more communities" is sound. It's good advice for any new player to any MMO in existence, and will lead to wins with enough determination.
