I think you've got that backwards. Certain countries will not allow one to enter on a passport with evidence of travel to Israel.
This statement is correct. Israel might ask more questions, but won't bar you entry based solely on Arab stamps. Some Arab countries will do this with an Israeli stamp.
As for dual citizenship - is perfectly legal to have dual citizenship with a US passport (so long as the other country allows this). However, US won't "recognize" dual citizenship - they basically consider you American only. Not sure about legal, but I have heard quite a few stories about uS agents giving a hard time to US citizens who show a foreign passport.
Im a dual US-Canadian citizen, an dUS knows per my Nexus/GE membership. I always enter the US on my US passport for sure. Sometimes I used to scan my Canadian passport when leaving the US at the kiosk. And I used to have both my Canadian and US passport in my UA profile, but I took the Canadian out - this always seemed to be used as default on my trips when booking on the site - I'm pretty certain it because it is first alphabetically.
