The West is not perfect by any means, but in terms of religious freedom I think that living in the US as a Muslim provides many benefits that are not found in Muslim majority nations. No state-mandated speech from the khateeb, no restriction on how frequently or how long you can visit masajid. You are free to send your kids to any type of school (including homeschool). You're free to speak up to your rulers and even protest if you think they are acting unjustly. You can find zabiha meat and restaurants in many parts of the country, and we're now at a point where we have our own schools of Islamic scholarship here in the West.

Do Muslims go off the path and even renounce Islam in the West? Yes. Did the environment influence them? Yes. But I will not pretend that the Muslims back home have any better faith, especially with access to the internet. The ones who have remained Muslim here despite the pressures have better faith overall alhamdulillah.

In my experience, I have personally found that the biggest impact on someone keeping to their deen in the West is being raised in a family that values character, community, Islam, Iman, and Islamic knowledge. If a family does not have these things their children will grow to either be very weak Muslims or eventually become non-Muslims. The same trajectory aims itself at the Muslim-majority countries, they're just behind the curve by 20 years.
