There are different kinds of view and philosophies in Islam. Despite of being raised as a Sunni Hanafi, I follow my own way of belief as I have my own mind to comprehend the universe as my own. You can say it's almost parallel with Nonduality - Advaita-Vedanta. I don't believe there is a God in X Dimension. I believe we all are a part of the one God forming the God himself.
If some belief is taking over as OP indicated, that should be giving what the believers need from it: relief and peace. So why people have to feel fear for it? I would fear, if I had something to loose if a belief would take over, such as financial revenue. There are very few religions which people don't have to pay because of what they believe in. Would I not be in peace if I don't have to pay? I am not paying anything to anybody, and I found my inner peace, just needed to think and read a little. People are too lazy, and don't like to think for themselves. They pay someone else to think for themselves instead.
So if there is a problem exists, problem is just about economics, not about the religion or beliefs.
