@Alon@BenRossTransit (i won't comment on whether it's racist or not for them to think so, but my understanding is Egypt's elites in particular genuinely fear Gaza's populations would add to sometimes violent strands of political Islam they already find difficult to manage, even with a willingness to indulge in, um, lapses of liberalism. Sinai itself is perhaps not a fully integrated province of a modern developed state, and though most Gazans aren't habitually Bedouin, they are a complication.)
