Sure it is. A lot of its laws are based on sharia, especially when it comes to family law, women's rights, religious freedom, etc
Right. So actually Algerian law is pretty much based on French law, seeing how it was actually part of France up until 1963. Not a colony, not a protectorate, it was a part of France. In fact, unlike many other countries in the Middle East, the law stipulates that women and men have the right to equal pay. If you want to base this on shari'a, be my guest, but it's actually so far removed from the truth that the very concept is laughable.

Usually I can pretty much understand why people think this way about certain countries in the Middle-East, and I'm really sorry to say it, but your idea of Algeria as being founded on Islamist principles is so ludicrous in its own right that I don't even know where to begin to dispell that myth. If you take a glance at the history of Algeria after the War of Independence, the violent crackdown on the FIS movement in the 1990s springs out immediately. The Algerian government is doing everything to keep Islamists out of the government.

No, I don't know you personally and really, I'm not that interested. But please refrain from making generalising statements about a country like Algeria, and as someone whose father was born in Algeria and whose family members and personal friends were detained, tortured or sometimes even assassinated because government officials merely suspected them of being sympathetic (!) to Islamist movements, it's not just ignorant, it's actually quite offensive.
