The command to submit to islam or die will NEVER be a normal part of everyday life. Most humans just don't operate that way.
You're right about that part (I hope). But for the rest of it...it's on the way, slowly but surely.
I read an article awhile back about a public pool in Canada that bans fathers from being present while their daughters take swimming lessons. Why? Because some muslim objects. I can absolutely see that happening in the US in the not-so-distant future.
By the way, here's the article. Sorry, I don't know how to link it.

You ignore long stretches of history in which that command was a part of everyday life in many parts of the world: in both what is now the Muslim world and in Spain, the Balkans and Sicily during the periods when they were under Muslim rule, the Christian or Jew who paid his jizya and kept his head down was left alone until some Muslim, any Muslim, not necessarily one in authority, felt an imagined insult or wanted some of his property, at which point a trumped up charge was brought before a Muslim court, which invariably found against the non-Muslim, but typically offered conversion to Islam as an alternative to the death sentence pronounced. This was an everyday occurrence.
