Pretty much why I was on the fence until the second attack on Utopia, and everything subsequently after.
Honestly, AvX started out good. The Phoenix was coming and nuking planets en route, the Avengers went to Logan and got bad intel, and Scott was willing to gamble Hope controlling the Phoenix Force for mutant survival over the planet's survival. And then... the Avengers attacked again because they feared the potential harm the Phoenix could bring and launched another unprovoked attack, then essentially cried foul when the mutants retaliated in turn. The act made even sillier when they already knew the Phoenix Force is unstable.
Now, if they showed Namor / whoever attacking first, then their fears were completely justified and I'd think more readers would side with them. It's sort-of like the whole Cap vs Tony in the MCU, where the former insisted on maintaining the avengers aspect of their name, while the latter feared greater cosmic threats and subsequently made Ultron. The balance to both sides of the argument came with Thanos' arrival and winning Infinity War.
Heck, the Avengers tie-in even had Rulk going against orders to infiltrate Utopia and assassinate Phoenix!Cyke, and the P5 just send him back bruised but alive. Like, dude... the final battle had the Avengers attacking Utopia again with clear intent to kill, and still we're supposed to believe the Avengers were the good guys? o_O
Lastly... I can't decide whether Wingstop Rangers is a wittier name than PENIS Five. Kudos to ya.
