Xavier is a liar and a straight up cheat..in case you missed X Men Genesis and X-Men #54(The Jean Grey pedo revelation)...Magneto's way is what Cyclops has been following all this time..doing the old school Cable 90s stuff where he would borrow from Xavier and Magneto and lead X Force with those methods. It finally backfired when Stryfe made his move and everyone blamed Cable and X force when Xavier was looking good as dead.
And Magneto was right...about Civil War and how mutants are seen in the world. That's why he can inspire the Psylockes, Briars, and everyone else to get behind his latest missions.
noone denies charles is a piece of shyt, but he could inspire people through peace. and the thing is i think he truly believes what he says. which is why he has so many loyal to death followers. scott is unable to completely sway people in the same instance, he rather keep a close knit group of loyalists than large categories. and i imagine he didnt win any friends among new mutants with avsx ending. but he was able to sway humans, which is something magneto was never capable of
and speaking of magneto, hes part of the reason mutants are seen the way they are. and he never seems to want to take responsibility for it. i honestly believe he fights because he doesnt know any better
