I don’t usually write meta or talk about my feelings, but in light of the posts below lamenting the lack of Erik love, I have to say: I love Erik. I’m here for Erik. I’m in this fandom because of Erik. I love Charles, too, but Charles doesn’t keep me here. Erik does.
Charles Xavier might be my sun and stars, but there’s a lot to like and admire about Erik Lehnsherr, and if people talk smack about him and reduce him to nothing more than a one-dimensional villain, that also would reflect poorly on Charles and his judgment, since he sees plenty of good in Erik. Both are formidable characters with stellar qualities and interesting flaws (the same goes for Raven Darkholme as well), so all of us in this fandom should try to give them their due and resist making sweeping black-and-white generalizations.
