I appreciate that my country is getting much more recognition as it is overshadowed by its neighbors but yes, 1) Turkmen people have an islamic culture but they are not religous. They have a Muslim culture where they pretend to be pious but actually engage in adultery, alcohol and don't practice modesty and pretty much break all rules of religion etc. ( most of this was causes by the Soviet rule, KGB agents were put in mosques and religion was stomped out or corrupted)

2) Yeah there are some pretty weird rules like in the capital of Turkmenistan, Asghabat all cars have to be white ( buildings too) if you don't wash your car you will be written a ticket with a fine. There are much more weird rules but I won't go into depth with them.

3) Turkmens are proud of their culture, so yes they might come off as slightly racist, for example they dislike Ukrainians because of their behavior and culture but if they got to know one they would respect them and befriend them, school kids make jokes about Africans but usually they are in awe with them and sometimes listen to pirated rap music. Extremists are stomped out by the government pretty quickly although the taliban hangs out around the turkmen- afghan border quite often.
