"They asked him nicely to leave." Adding please doesn't make the request polite. They joined half way through an activity and decided to ask the person who was already there to leave the activity. There is nothing polite about that. "He replied rudely." How so? He stated what his intentions were and what he was doing prior to them joining him. "If he was kind in how he replied they most likely wouldve not been assholes." If his answer was anything other than what they wanted to hear they were going to be assholes. They attempted to get him to join their fireteam so they could kick him from the activity. The only reason why the back and forth took place was because they (The 2 spoiled brats who joined halfway through) couldn't force the original poster to leave the game.
