The Quran explicitly prohibits disrespecting other religions. Those who try to forcibly convert others aren't following the teachings of Muhummad.
As far as I know, only a fraction of the Islamists called “ Sufi ” respect other religions and people of other religions, because they believe that the other religions and people of other religions should be under consideration of God ( Allah ) and the Islamists have no right to oppose or harm them.
Quran 8:38-39: “Say to those who have disbelieved, if they cease (from disbelief) their past will be forgiven… And fight them until there is no more Fitnah (disbelief and polytheism: i.e. worshipping others besides Allah) and the religion (worship) will all be for Allah Alone [in the whole of the world ]. But if they cease (worshipping others besides Allah), then certainly, Allah is All-Seer of what they do.”
Quran 2:193: “And fight them until fitna is no more, and religion be only for Allah. But if they desist, then let there be no hostility except against wrong-doers.”
Take note that within these 2 verses, the Muslims are commanded to fight until the religion of Allah prevails.
Qur’an 3:83: “Are they seeking a religion other than Allah’s, when every soul in the heavens and the earth has submitted to Him, willingly or by compulsion?”
Surah 3:83 is very interesting. Notice that Allah has revealed unto us that some have come to believe in Islam, not by mere willingness, but
compulsion.
Sahih Muslim 1:33: The Messenger of Allah said: “I have been commanded to fight against people till they testify that there is no god but Allah, that Muhammad is the messenger of Allah, and they establish prayer and pay zakat.
