I spent November and December in Abu Dhabi in 2019. The hotel I stayed at had a Christmas tree in the lobby. Several times groups performed Christmas carols. What was amusing about this is that a bunch of the locals turned out for the Christmas carols with their kids. Taking pictures and having a good time. There are a number of countries where Muslims seem to have adopted Christmas as one of their holidays. Strange but true.
What people won't tell you is that here is about 30-50% of the Muslim population agrees with it while a significant portion of that number would be willing to kill non-believers.
