It's also ignorantly false. Never is a very long time. They were the same peoples or coexisted peacefully for the majority of known history. Only "recently" has there been divisiveness.

what about the whole slaves in egypt bit?

Aside from the fact that ancient Egyptians were not Arabs, mainstream history and archaeology no longer consider the Exodus described in the Bible to be a real historical event.

Here's one article about this, from the Israeli newspaper Haaretz:

> [The Exodus] never happened. For decades now, most researchers have agreed that there is no evidence to suggest that the Exodus narrative reflects a specific historical event. Rather, it is an origin myth for the Jewish people that has been constructed, redacted, written and rewritten over centuries to include multiple layers of traditions, experiences and memories from a host of different sources and periods.

Those weren't Arabs.

You get the same type of nonsense in regards to east asia. Like china, japan and korea have never gotten along and had been in an eternal state of war when in actuality, they had gotten along for most of the past millennium with the 20th century being an exception.
