I just got offended because he kept saying : I still think it's fold, or shove, like 3 times in a row.

Arguments made by me were :

1)Opponent will not get it in with worse, unless total donk
2)You let him keep bluffing if u call
3) (related to 1) You're very deep.

That's why fold or shove is clearly not the best play, cuz it allows him to play perfectly against your range. If you shove, he calls hands that crush you, if you fold you allow yourself to be bluffed always this deep, whereas calling forces him to barrel bluff to get you off your hand.
