Devotees of Mary do not wear hijabs, nor do they wear long dresses for everyday wear. They also follow Mary’s Son who taught the opposite of everything Mohamed taught about women.
They also tend to assimilate into cultures rather than overturn their host country’s laws and replace them with Islamic/Sharia laws and governments.
Yes. I don’t believe their invoking of Jesus and Mary is going to be effective for their cause, except among low-information people.
