You can hide youtube comments btw if they disturb you. It's pretty much always like this. Yesterday I watched my hometeam's game in a European competition against a team from Austria. There were like 5 Austrians that went full ncoloradojazz and commented on the jerseycolors(magenta) and presumed homosexuality...
The game Ger v Tur was the worst. Turkish fans have a hard time accepting that Germans with Turkish migration background elect to play for Germany - "Discussion" moved to soccer quickly, where a handful of half Turkish guys play for Germany. Add to that other multinational guys on the German team and a dozen of Greek spectators(Who needed Germany to win by 7 or more to remain in the tournament) and you have one of the most toxic situations on the Internet right behind child pornography and crazy religious content. Many Greek basketball fans are usually as crazy and racist as Turkish and Serbian/Croatian ones.
