That's not how things really are.

We have many muslim minorities in Russia. Shia, sunni, some other lines. None of them have anything against Christmas trees. Taking in account that Jesus is one of greatest prophets (Isa) in Islam, there ar no any background for any muslim to hate or be offended by Christmas celebration. Also, there is no any aversion of celebrations of Ressurection or other Christian holidays. It's not a rare thing to hear "Christ has arisen!" on Ressurection holiday from muslim sellers on city markets and trade fairs, muslim colleagues or neighbours.

It is not hard to find something like this photo https://www.alamy.com/181231-damascus-dec-31-2018-syrians-celebrate-on-the-new-year-s-eve-in-damascus-syria-on-dec-31-2018-syria-damascus-new-year-celebration-ammarxsafarjalani-publicationxnotxinxchn-image564388845.html to figure out what Syrians think about Christams trees. There is no any reasons for Syrians to be offended by Christmas trees at all.

However, there is one tribe that hate Christ and everything connected sincerely and thoroughly. Cristmas trees too. And, suddenly it is not muslims. Again, suddenly, exactly that tribe is behind bringing muslims in enormous amounts into Christian countries. And, again, by completely occasional cohencidence they are referring muslim minorities they bring into country as an excuse to get rid of Cristmas trees and anything christian.
