Any time someone says “Muslims always” or “Islam is inherently… ____” return to this basic fact. Not only is that bigotry, the basic reality is that there are so many Muslims on Earth living in so many different places with different cultures that any kind of generalization is at a face level absurd like saying the world is flat.
The fascination to Mohammed is because he’s the last prophet sent by Allah, similar to how christians portray Jesus (not exactly the same since Christians believe Jesus and the Holy Spirit is also similar to God, whereas in Islam prophets are just messengers of Allah, and cannot be compared to Allah.)
