Criticize political parties and their leaders, don't engage is stereotypes about who you think their followers are. This is especially important if you want those leaders to not have any followers. Criticize the actions of governments and institutions and avoid making generalizations about their citizens, especially if you want these governments to fall. Of course if your real point is to wipe out a whole nation then you can continue using terms like "Arabs", "Israelis", "Muslims" and "Jews" - go ahead and continue to use those terms if you want to defame and incite to violence, but don't be surprised with the consequences. Being a socially responsible writer will perhaps make for longer and more awkward sentences, but if the consequences of elegance and good rhetoric is defamation and violence, better to awkward and long winded - especially if your intention is to prevent violence and inform the public.
