I would like to point out, that although you seem to take a position in your writing as though you are talking to the entire audience of people reading the thread, you are replying SPECIFICALLY to Ralanr in these posts, and thus you should respond to him as though he is the only one you are talking to.
Ralanr, never insulted you, never called you a "filthy Yasuo main", he simply made a suggestion on how you handle your posts and to be a more constructive person/poster/writer thing.
"Grow thicker skin" is not an insult, its a suggestion: Let me rephrase what he said a different way:
If you came to the forums to expect all your ideas to be agreed upon, then frankly you need to grow a thicker skin. Especially when Yasuo is a hot topic.
If you have been on the boards at all, you should know that EVERYONE will come into your thread to disagree with you, especially if you are talking about Yasuo. You should take care to remember that and be prepared, because otherwise you just become another one of "them": people who shout opinons on the boards but add no meaningful discussion.
All of that is summed up in "you need to grow a thicker skin". Its obvious why he chose to say it that way, much fewer words. XD
EDIT for the record, I love Yasuo as a champion, have no problems destroying him when he shows up in top lane with me. I think he is still a bit underpowered and a difficult to balance champion.
