"Yes, we forget this, but that is what Islam is all about. For Muslims, there is only Islam and everyone must submit to it, either by becoming a Muslim or by being a slave to Islam. One or the other. That is how they proceeded, enslaving all those who did not want to submit. Let us remember the religious orders: the Trinitarians and the Order of Our Lady of Mercy, which were founded to rescue Christians held captive as slaves by Muslims. They raided the coasts of France, Spain and the entire Mediterranean, kidnapping Christians and taking them home as slaves. This is still in their minds."
