Because these are super hero comics, so things HAVE to go "pew pew" and "kaboom" either right away or eventualy.
That's the whole premise of such comics. Or else fancy outfits and costumes, super model and alien looks, simplified logistics and organization, wild all over the place super powers and all the other visuals would need to be excluded too.
It would be all people in suits throwing rhetoric at each other over and over on media. People in lab coats and protection suits looking at tiny plastic and glass vessels, inserting tiny drops of clear looking liquids into them and then looking at confusing looking stats and graphics, over months. People in various outfits sitting behind computer screens all day and manipulating informations and fabricating social media opinions.
And all because one part of the human population suddently has something like the ability to feel what other people think via the sensing the bio-eletricity in their nervous system. Not manipulating weather, creating magnetic fields, being able to turn into stone, ice, fire, gas, comic letters, etc.
And not just in singular scenes and summaries, or as one-issue side tracking. It would be the whole thing.
Of course you could make a comic like that. But it's not what X-men is about.
That IS "pew pew" and "kaboom" with the occasional big lettered speech or scene of people in suits but all that is just sidetracking leading to the action.
With a metaphor of various injustices against people of "otherness" from the defined or pecieved norm thrown into the mix, to the point where the mutant metaphor contradicts itself at times.
