It’s not Islamophobic. It is, very simply, Christian. If they do not like to live in a Christian country, they should leave. They are the most intolerant people on the planet. If you disagree with them, they attack you physically.
Any religious practice other than any given specific sect of Islam is Islamaphobic from the perspective of that sect. Muslims tolerate only those Muslims who are in their own community/mosque.
For a Muslim to be in a room where anyone of another faith is witnessing to their faith is an intolerable insult to Islam.
