Actually conservatives contribute to charities at a far higher rate than libs.
"Dr. Arthur Brooks’ 2006 book, “Who Really Cares? America’s Charity Divide: Who Gives, Who Doesn’t and Why It Matters,” quoted studies pointing out the differences between the giving habits of political liberals and conservatives. In one study, households headed by a conservative gave away 30 percent more money to charity than households headed by a liberal ($1,600 to $1,227) even though the household income of liberals was 6 percent higher.
Brooks cited other studies concluding that conservatives are more likely to volunteer time to help the poor than liberals — an average of 12 percent more total hours each year. And they are more likely to donate blood. “If liberals and moderates gave blood at the same rate as conservatives, the blood supply in the United States would jump by about 45 percent,” he wrote."
