The NA players watch EU LCS only to insult the players and the whole region. They also do the same thing in the NA LCS.
For every arrogant EU player in twitch chat, there are about 10 arrogant NA players.
Also, making fun of all the people that died in WW2 and the people that died in the airplane Germanwings is kind of crossing the line. (Not to mention a few people saying that WE should die.)
Another thing that annoys me a lot too is the names they call us.. "Eurotards", "Europoors". I knew Americans were arrogant people but the ones in twitch chat are beyond arrogant.
