I too agree with you on this. People shouldn't judge an individual because of what group they are part of, or what roleplay groups they participate in. Ever hear the term "guilty by association"? That mentality is pretty intense in this community. "Oh that guy is part of that pack. Therefore he must be a troll/powerplayer/bully." or "She's part of that clan. She will probably come kill our kits in our clan." Come on people, that's not always the case here. Just because someone is part of a certain pack/pride/clan that has a bad rep, it doesn't automatically make them bad too. It all depends on their own actions, and not the actions of their associates.
I have a friend who has a character that is part of a clan that has a very bad reputation amoung the warrior cats of Flourite Plains. She doesn't act aggressivley, or powerplay, or try to kill any of my characters. In fact, she is kind, sweet, and a friend to my unicorn fox character. Just because she is part of that particular clan, it doesn't mean she's evil. Quite the contrary, she's as sweet as honey. I have other WC friends who were part of clans that supposedly had bad reputations. They never acted in a bad way toward other people.
And as for the members of the TEC, I never viewed them as trolls at all. I don't know where people get the idea that members of the TEC are all trolls and bullies. It could have been one or two members that did go around to troll people, but I'm pretty sure they are no longer part of the clan due to their rude behavior. I have plenty of friends in the TEC group. They are happy, friendly, funny floofs. I have never seen any of them troll other people. Not once!
So that's my bit of opinion. I hope it made sense.
