What would probably happen would be employment of Taqiya - lying to unbelievers, where official leaders of Muslim community in France would publicly claim lots of thing like aforementioned verses in Quran are no longer valid, how Islam is
religion of peace etc...
Christianity, my own Hindusim, Judaism, Buddishm,
etc. but we all have left those behind, and none
of those can obscure the tremendous contributions to
peace, universal brotherhood by these great
religions.
