For example, his brother Roy opted for Islam over Christianity, as Obama recounted when describing his 1992 wedding.
The person who made me proudest of all, Obama wrote, was Roy. Actually, now we call him Abongo, his Luo name, for two years ago he decided to reassert his African heritage. He converted to Islam, and has sworn off pork and tobacco and alcohol.
Abongo Roy Obama is a Luo activist and a militant Muslim who argues that the black man must liberate himself from the poisoning influences of European culture. He urges his younger brother to embrace his African heritage.

Yes, and my uncle is a devout Buddhist and a personal friend of the Dalai Lama. (No joke.)
I do not adhere to his religion, but as an American, I support his right to practice it.
Loving a family member does not mean that you share the same beliefs about God, necessarily. It means accepting your loved one as they are. Obama accepts his brother. That does not mean that he and his brother attend mosque together.
