The quote about giving is reflecting on the happiness one feels when they give personally to another in need. Not forced giving where elites decide who deserves the money and steal it from your pockets.
Republicans wouldn't have a problem with the quote about a good work ethic either. It isn't what you do for a living that determines your self worth, but that you work hard at whatever and pay your own way.
The third one was a quote he gave in an interview expressing his personal beliefs on gay marriage and later apologized for his strong language. If the man thinks the federal government has the right to define marriage for all then I disagree with him just like I disagree with Obama supporting gay marriage as a national right. It's none of the damn business of the federal government period. And the special interests groups on both sides of the issue need to come to realize that one.
