Sometimes - not frum people are frummer than frum people!
Example: Jackie Mason wasn't frum. But he helped support his relatives [brothers and nephews] who sat and learned.
I know a lot of poor avreichim who have wealthy relatives who are frum and yet don't give them a penny.
The Halacha is that when it comes to Tzedaka, relatives come first.
Don't judge people by the size of their yarmulka or color of their hat. Hashem knows the truth.
