Why not make harmless concessions to Muslim extremists - God forbid! Whatever next?

Like, refraining from exercising all our rights of free expression and not publishing images of the Prophet or making fun of him or Islam.
Like, restraining our natural instincts and not invading and occupying Muslim lands or killing Muslims - or, anyone else for that matter.
How about becoming less dependant on Arab oil or refraining from attacking Gaza?
What about the French allowing Muslim women to wear the full burqa, if they so wish?
And letting them have their mosques in western Europe, even with minarets?
