I assume you are Draxter? I also assume you are fairly new to Halo race. Let me correct you on one thing:
...i killed him when he was attacking me...
That is not true. The first time I kicked you for playing slayer I had not fired a single shot nor thrown a single nade. You and I were at red base of Danger Canyon with plenty of hogs available to race in and instead of getting in one of those hogs to race you decided to walk right past that hog to attack me while I was trying to get in my hog. And like you said yourself...you killed me twice that way. Then you were kicked.
The way you behaved in that situation is not a banable offense and only requires minimal correction. Your inaccurate description of the incident in this thread though, specifically your incorrect assumption that I attacked you, tells me something about your "attitude" in the game. You are too focused on the slayer aspect of the game. So much so that, for short periods of time, you forget all about even trying to race until you have gotten your kills and you assume everyone is attacking you. Well I wasn't, I was trying to race. You will also find that most veteran racers will, given a choice between attacking a lone enemy and getting in a hog to race, will choose not to attack so they can race against that enemy instead of fighting them in a slayer battle.
Now once you had been kicked your attitude took a turn for the worse and you became very rude and argumentative as well as continuing with your slayerish game play. As a leader of this clan I can guarantee you that my warnings to you were all legitimate and you will need to change things to keep racing in our servers. First you will need to change your rude and argumentative attitude so that you can listen to and benefit from the warnings you receive. Secondly you will need to actually take the warnings you get as constructive criticism about what changes you need to make in your game play...and try to make those changes.
One of the times I kicked you was because of a totally inappropriate conversation you tried to start. You started to say something about calling people racist? There is no need to talk about anything like that in our servers. Our servers are provided to the public to race in not to have controversial discussions. We also try to keep the atmosphere of our servers "family friendly" because we know that children play in them and again there is no reason to expose children to a conversation like that when they are here just to play a game.
To sum it all up the real problem you have is your attitude...it is disruptive to the server and we can't tolerate that. Your game play is only a minor problem and you do spend most of your time racing but you do get caught up in things other than racing too easily. It is entirely up to you on how much effort you want to put into changing that.
