One can support "stop killing." It's presumably what most people everywhere want.

I never used my Birthright privilege. Not because I was afraid to go there—I still am planning to go there—but because when I was in my early to mid-twenties, I met a Palestinian woman who'd been forced to flee from Jerusalem when she was 12 and was never allowed to go back. And I don't think it's right that I'd get my plane ticket paid for and she couldn't set foot in the city where she was born.
