Islam in what sense? Religions can mean multitude of things: a religion can be simply a set of beliefs seperated from your day-to-day life, it can mean a way of life, it can mean a culture, it can become the institution of a society ... As a religion, I think islam is as evidencless and thus kinda silly religion as every other one. As a culture or an institution of society, I think islam is destructive. As a way of life, I think islam can make you do good things you could do without it, but it can make you do bad things you wouldn't do without it (just like any other religion).
