Trump adn Obama's birth certificat

The birthers ask legitimate questions since in the U.S. birth is important legally and there is no reason (supposedly) to hide Obama's marks, religion, or source of funding. Everyone knows Bush junior's place of birth, average marks at university, drinking problems, religion, and source of funding. Why should those same factors be hidden for Obama when he has a Muslim Kenyan father, a Muslim step-father, and an unknown source of funds for his university education? This is not the same thing as calling someone a communist or a fascist. The latter are baseless attempts at killing character, not serious questions to try to understand a person's potential motives and policiies. I don't like Trump but am glad he made Obama produce a birth certificate.
