First of all, I am from Isreal, and to anyone living under a rock, there is an escalation in the Israeli-Palestinian conflict currently.
So this is what happend, I solo queue into a match on split everyone seems nice we have a good comp, and everything fine. We win the pistol and the following round then Reyna, Cypher, and I realize we are all from Isreal. Then in the third round sage runs down mid with spike, at first we thought she was just throwing, she started walling us off, slowing us, giving away our position in chat, and taking the spike and throwing it over to the enemies. We kept asking in voice chat for her to stop throwing or just stay AFK in spawn, then near the end of the half she types in chat something along the lines of "fucking Israelis" then it became clear why she was throwing. After that our Omen from UK told her to stop being a prick, but the enemy Sage, Breach, and Brim started cursing us in chat and teaming with our Sage. With some miracle, we managed to win the game even with sage throwing the game, nevertheless, my team and I had a horrible experience.
I am posting this to ask people to please leave politics out of the game and let everyone play.

TL;DR
Antisemitic Sage was throwing because I am from Israel.
