Sharia law is not consistent. It can vary widely. The problem is when it is held above all other laws. Multiculturalism does not work. It always creates conflicts. Europe has been struggling with this for years. Headscarves and marriage laws are a good example.
Modda, you sound like an ex-Catholic with and axe to grind. You judge people you don't know anything about. I studied Buddhims for several years. There are some famously corrupt Buddhist just like there are corrupt Chritians. Every human institution has some corruption. You live in a very small world.
