It’s more complicated than that. My sister is Satmar, and lives in Williamsburg. She has a Satmar neighbor who told my brother-in-law that the only reason he makes a Sukkah is because of his wife. He, personally, eats at MacDonalds from time to time.
Sadly, there are many frum-looking people who are not really frum at all. Who can say how many frum people there are when we don’t always know the truth?
