I'd say that the spread of any religion is a problem, particularly with a religion that has extremist sects such as Islam.
As a religiously neutral person (atheist) I consider any increase in religion as bad, no matter which one. Religion as a whole is something I look down upon, as it is essentially picking sides. Atheism is superior (without trying to sound like a neckbeard fedora euphoria person) because it is THE definition of neutral, which is why I think it should serve as the stepping stone in society.
