I'm hella rusty on my european history (european history never really did it for me) so I am mainly working with the google as my supporting evidence, but iirc while the Carnation Revolution was a remarkably unusual demonstration of a largely peaceful transition of power the protest didn't result in the overthrow. the actual military coup had already begun and the incumbent government already relented by the time the civilian protests began. also it was not the first or only coup by the MFA, it took multiple attempts (not just from the MFA) and years of build up frustration with the powers that be to accomplish that ultimate goal. even then there was still blood spilled, astonishingly LESS blood than your usual military overthrow (only 4 killed and 45 injured civilian casualties according to google) but regardless, violence alway tends to find revolution. the Carnation event was a celebration of the fall of fascism, it was not the action that removed if, that was the military coup. the Portuguese government didn't just up and stop being dictatorial because of peaceful protest, it was an overwhelmingly successful military coup that changed the government. point being, one day of peaceful protest didn't change Portugal, that's just the mythology like the American dream.
so my question is, are you advocating for a militant mutant coup of human society to make changes from the top down? because if that's what you are proposing they do then I guess I'm fine with the X-Men moving out of Krakoa back to their usual humanitarian efforts back at the Xavier Institute. although, I don't see them reaching their goal without humans killed some more of their brethren and children. oh well, you know what they say about eggs and omelettes.
