No, as a matter of fact, we're not -- we're talking about whether Hebrews were ever slaves in ancient Egypt. Hence the title.
One of the more recent theories I find worth considering is that the Egyptians at one point encouraged Semitic tribes to settle in the Eastern areas of the Nile Delta as a buffer against the Hittites and others. After a few generations the Semites became so numerous that they were perceived as a threat and were then subjected to mass conscript labor, i.e. slavery to Pharaoh. It was from that servitude they were led by Moses. Who knows? Main point is the Bible is not a collection of fantasy and whole cloth myth.
