the crusades whether you agree or don’t agree with them, cannot be compared to the Islamic conquests led by Muhammad’s immediate followers in order to spead Islam. In our faith, we do not have conquest wars to spread Christianity and here you can compare Jesus’ disciples to Muhammad’s to see the difference in ideologies, not the crusades that happened after Islam and because of Islam.
Just some days ago, thousands of Muslims attacked a church where Christians prayed for the first time in Egypt. They were shouting Allahu Akbar, only Islam will prevail, we don’t want churches, no churches allowed here and the Christians were forced to interrupt the mass and many flew to their homes or where trapped inside the church for hours, with thousands of Muslims outside carrying sticks and throwing stones at the church and the Christians could do nothing but scream for help on tv. Whether Islam teaches this or not is not the question, but it is an example of what it is to live as a second class citizen among such people, even if not all Muslims agree with what happened. After all, there isn’t one Islam, there are moderates, there are extremists, and fanatics and people following their sheikhs, and all can back up their hatred from either Quran or hadith and nobody knows who will fill the mosques in Europe or any other country.
That’s why it is a risk, because Islam is not a religion you keep to yourself, but an ideology where others are second-class citizens. where the ummah is to live only under Islamic teachings, where Islam must dominate now or later, be it through wars, poltitics or economics and there is no separation between religion and state.
