I guess you would have to watch atleat one thing with him to understand his views and the racism in x-men world . To sum up in a horrible way magneto is mostly an anti-hero guy who think sometimes violence is necessary to get his kind the basic of rights like to exist without being hunted .
He was a relatable character, in what he wanted, but he forced the Mutant gene on that dude, then that guy died. I just remember he wanted to rinse/repeat that on the whole city (not knowing everyone would die). I think it's an oversimplification to say he's right, but he's definitely relatable, which makes him a terrific villain.
