Why are so many french people so hostile ingame ?

lately french speaking people have been so toxic, for the most stupid thing ever ivern top refuses to push, and gives out free kills and gets some himself 30 min later, he has been sticking to their second tower, while the enemy keeps invading out mid base tower

we tell him to push, he continues to ignore this , and play around in the jungle while we are having trouble defending, the lee had to solo his grumps because ivern refused to help then continues to call down his cs , jhin had 177 cs , ivern had like 50 ish , calling us more stupid french stuff

keep in mind, he was also french, but didnt mind it, and continued to play, a good lee at first but the more furthur we got in the game, the more my adc got annoyed, by how those two kept talking in french, and insulting, calling us noob etc(only ivern) lee kept silent, until the end , then started as well

later lee openly defended ivern, besides his insults, and refusing to push , when we are on the losing side i dont get it , is there a secret french code that forces french people to auto.m take the side of his french teammate no matter what he does ?

any french players who arent like this ? also if so, what's your opinion , on this //

tbh i dont hate normal french players,just certain ones, like in the example above sorry for the long post [slayer-jinx-catface]
