Chris Claremont even said when he started his run (which includes such iconic arcs such as Dark Phoenix Saga and Days of Future Past) that he brought in new members mostly from different countries and ethnicities since (at the time) X-men was a metaphor for racial discrimination so he felt having a team work together despite coming from so many different places was an important aspect.
He even spoke in 2021 about the importance of diversity inclusion in X-men in 2021.
The fact that anyone would complain about “woke shit” when it comes to X-men of all properties just baffles me. Then again, people acted shocked when Black Panther movies comment on politics (also, Stan Lee created the character upon discovering he had plenty of black people reading his comics and he felt like he was ignoring them by having no black leads, another comment that if he had said today would be labeled “woke” by some) so it shows how little some people seem to be about the themes of these series that have been around for decades.
People complain about politics in the comics movies. When it’s pointed out the comics have them, they then try to say only modern comics have them. Then it’s pointed out comics have had politics in them for decades (Green Lantern/Green Arrow from the 70’s was far less subtle about its politics compared to most comics even today, and yet it’s consider a classic run). So then they claim it’s the new characters being introduced for political reasons that is “ruining things”, and so it can be pointed out Black Panther was created for these “political“ reasons, and Green Lantern John Stewart was introduced in the aforementioned run and his first issue was all about civil rights. Bendis‘ creation of Miles Morales, who became the lead of one of the most beloved Spidey films ever, was partially inspired from his daughter wanting more black superheroes to follow. And of course, the very concept of new characters also taking the mantle has been a thing in Marvel and DC since the 50’s.
