Oh! I see, prejudice against mutants is just like prejudice in the real world! Because...why?
I mean, black people, gay people and Latinos(to name a few who Marvel claims the X-Men are a metaphor for) and such can't kill people by looking at them, for instance.
The only time this worked was "God Loves, Man Kills," and mostly just in the first two pages. Otherwise, if you really look at the message that sends, it's actually kind of ugly and counterproductive.
