I'll try to be more accurate. Saudi Arabia funds mosques all around the world to spread the official Saudi version of Islam, which is not just slighly conservative.
Saudi Arabia also trains a good share of clone Wahabbi preachers (normal, they are the only ones who have money to do so), whose speeches are fearsome.

Many of the Mullahs in Europe were trained in Saudi Arabia and they efficiently kill any kind of alternate vision and practice of Islam. My mother's husband is a devout muslim (egyptian) and has changed mosque twice in the last three years, beeing fed up with Saudi-inclined "scholars" who try to force fear and hate in the hearts of men. He found a mosque where the majority is Turkish, so is the Mollah and the man speaks of faith and personnal Jihad, not politics and aggressive Jihad.
Religion was a political tool in the hands of Ibn Sa'ud to come in power, and is still used as a political tool by Saudi monarchs today, that's the reason why I can't trust an official Saudi religious authority.

So to answer your question Farhad, what I see is Saudi Arabia funding a very conservative stance at home (calling them "extremists" is a question of viewpoint, I would call them so) and encouraging a notoriously perverted form of Islam abroad.
