wtf is wrong with some of these players

Mentioned in chat how I didn't want to play with an AP J4 (seeing as how we lost and how it wasn't useful you might see why) and that's it. That's literally all I said "I don't really feel like playing with an AP J4" and of course I still played the game cause we had some good pushing back and forth and I'm not a leaver. But somehow my comment at the start of the game turned me into a black sheep for the other 4. I probably said that 5-10 min into the game, and left it at that and went about my business. But toward the end of the game Yasuo started bm-ing me unprovoked, saying how AP J4 likely had more damage than I did, which a) is a fair statement because his items were geared for much more burst and b) if you think damage is the only stat that matters i've got some news for you. So I said "who cares?" and he goes "u do" like...you mean the singular comment I made about only not wanting to play with ap j4 15 minutes ago? and said nothing after? and said he gave ap j4 his honor despite the troll build said to "just report leblanc" when I literally did nothing to provoke anybody and just wanted to play the game. I'm not worried about their reports because I wasn't mean in return nor was I toxic in any form but like how are some players so delusional? Holy shit
