Non-story. He's defending his franchise.
That being said, he does have a slight point. X-Men does have the potential to stand for a lot more than the average comic book serial. It had for a long time as well. You could actually write a solid essay on the X-Men series.
This.
And it's kinda obvious since DC built a lot of their franchises on archetypical heroes. Superman especially because he was originally modeled as a modern day Hercules, hence why originally he just had insane strength and could jump high/far. Morrison paid tribute to that in All-Star Superman with the twelve labors of Superman, and it's also why he had guys like Samson and Atlas pop up in the story early on.
Marvel on the other hand rose to fame due to the incorporation of socio-political elements that made them more down-to-earth and relatable to our struggles. So there was always more room to go 'deeper' there than there was for DC.
They made superman edgier and people bytched because he wasnt the campy goofy Christopher Reeves that people assumed superman is supposed to be. Ignorant fans are not knowing that DC has been steady trying to shed the boyscout image for years. Superman was ready to kill to darkseid in the justice league cartoons and actually killed Lex in an alternate timeline.
And wants even more funnieris that golden age superman was a cold hearted psychopath.
Nobody wanted campy, goofy Donner/Reeves Superman, that's idiot talk. I never get why people think that just because people weren't happy with MoS they must be Donner worshipers. There's a ton of play room between those interpretations and as many comics and cartoons have proven in the past decades, the perfect balance for a modern Superman lies somewhere in between those two interpretations.
