From what I understand, it's a secular movement but it's not anti-religion. It's rooted in socialism and Arab nationalism way more so than religion, although I think Islam has 'official religion' status.

Morocco OTOH is a Muslim state, with most laws being secular except for family laws, sexual freedoms, and inheritance. Before Western colonial times, the Moroccan royal dynasty built a lot of its soft power on spreading Morocco-based Sufi orders South, and one of the king's titles is "Commander of Believers", which is how caliphs of the original Muslim caliphate called themselves.

People like that he has this role because it helps keep Islam somewhat out of politics, but it cuts both ways: it's harder for religious conservatives to argue against more liberal laws when the institution (called the "Makhzen") proposes them, but it's even harder for individual liberty advocates to argue for a more progressive society when it goes against the Makhzen's plans.
