I know a lot of Christians and other religions where people can openly say they are atheist openly and their family(and society in general) is okay with that. The problem with ISLAM is it is so dogmatic, no one can oppose it irrespective of education, in fact they double down when questioned or shown facts and preach tolerance to others or point other religions quotes. This is what i hate about ISLAM. There is some thing deeply wrong with it, they can not take criticism even if you are in the STEM field.
