Insulting in a different language is a moot point, sure they might not understand what you're saying at first, but they are resourceful and if they think you are behaving inappropriately, they WILL act.
Many people, myself included know languages other than English, but do you see insults regularly? NO! Don't resort to immature behavior making this forum just another flamer board with little to offer WC newbies and veterans alike other than constant bickering.
I hope you guys were just joking about this.
