what you're describing is pretty consistent with general Jewish strategy of marking themselves from everyone else,
All of 'kosher' is just to prevent Jews from interacting too much with Christians and Muslims and assimilating into the dominant culture. That is where the separation originated: with the Babylonian exile, which in retrospect wasn't serious but it allowed them to build antibodies when living in alien lands was serious.

Also they use poison against their enemies so they know it's a good idea to only allow other jews to touch their food to avoid the same fate.
When did 'they' use poison against 'their enemies'?

OK, so no actual instance, only a 'plan'. And way after kosher rules were developed, so the guy's explanation for kosher makes no sense.
