How do I get suspended for this

Well I just got a 14 day suspension for acting angry at an inting draven. Didn't hard flame, basically just kept saying have fun being banned (i think i said he was bad once but no direct insults apart from that). He was legit standing under tower and refusing to fight the entire game as well as flaming his sup for every death and typing "im done" several times, on top of typing in /all to come kill him. I was trying my hardest not to be tilted but I got suspended almost immediately after the game and it was all for expressing tilt towards draven (without even flaming). This has me extremely angry-iIs there a way I can contest a suspension, or do you think this was deserved? It is slightly tilting that someone can soft int the entire game and receive no punishment while i get suspended for being mad at that. Chat logs for my suspension are below.

Game 1 In-Game kingingernator: did kingingernator: btw kingingernator: 10 times kingingernator: draven goes 0-2 in lane bc bad then blames on everyone else and ints haHA kingingernator: lol rip ur acc draven kingingernator: have fun climbing out of b5 again kingingernator: nice skin kingingernator: rip moms money kingingernator: lol kingingernator: ur inting kingingernator: chatlogs cant carry u kingingernator: from 9 reports kingingernator: ur afk kingingernator: why so its a 0v2? kingingernator: ur already afk kingingernator: and u do need him kingingernator: considering u blame him for ur deaths kingingernator: so toxic kingingernator: u didnt say anything lol kingingernator: u afked kingingernator: said im done kingingernator: typed in all chat kill me kingingernator: proof is there kingingernator: on top of tht u havent gotten a minion in 5 minutes and are behind in xp kingingernator: hope u get permad u are what makes this game so unfun kingingernator: lol hes mad bc im angrfy at him for inting/afking kingingernator: again? kingingernator: said you were done b4 kingingernator: ???? kingingernator: me? lol kingingernator: drav is inting and keeps saying hes done kingingernator: he didnt say anything other than stating he was done trying and typing in all to kill him, but he has been afk under tower and flaming braum entire game lol kingingernator: nah is a troll kingingernator: wants to get me banned after he ints but i have faith in riot kingingernator: see look harassment haha kingingernator: proud of you draven kingingernator: ye kingingernator: what u talking about kingingernator: was a reference to you getting banned lol kingingernator: good ult drav kingingernator: wp ez lol kingingernator: no kingingernator: tryn didnt do anything lol drav has been trolling all game kingingernator: oh kingingernator: i didnt see tht

I snapped a little in the beginning bc he started to afk before 10 minutes after he died and blamed it on his manaless braum. Ik that was toxic but not nearly as toxic as ruining the game for everyone else? After that I tried to keep it reeled in and didn't flame. Btw the two comments at the end saying proud of you and good ult were not even sarcastic he genuinely did good (he started trying after me and tryn were fed). Sorry if this post was a mess/disorganized it's my first forum post and im also heated.

Edit: Ok say i deserve this, it doesnt matter but the main problem for me is that the draven who singlehandedly ruined all 9 players experience gets away with it as the victim while i (and probably whoever else he reported, considering how many people were flaming him) get the punishment. Idk how slight chat toxicity is somehow a worse offense than inting and flaming all game. I guess my real issue is how easy it is to soft int a game and not get punished for it.
