Conservatism in America is always associated with a decision making process dictated by religion. He attacks creationism with evolution and the Christianity's disapproval of euthanasia and abortion. These generalizations are neutral since the right will stand by these fallacies.
Where the bias comes to play is when he says "affirmative action is racist" and "taxation is theft". This is not what conservatives believe but instead either skewed to easily argue a liberal point of view or just a lack of understanding of what the right thinks.
Most of the right don't support affirmative action not because it creates a disproportionate amount of minorities but because it creates a disproportionate amount of smart people. For every average minority that gets into an above average school, an above average non-minority must now go to an average school. This aligns with the liberal ideal that "Since life isn't fair, we must intervene to make it so".
When Republicans get elected to office they don't try and put legislation into place that does away with all taxation. Simplified: the left supports a higher less equal taxation and the right supports a lower more equal taxation. When the right is lowering taxes that's only because they are balancing out programs implemented by the left that don't align with their economic policy.
It's a tired argument. The left finger points that wealthy Republicans are selfish for not being willing to support people that are poor. The right says "It creates a net negative because it results in a lack of economic incentives for individuals. Feel free to support them yourself if you're so selfless". The left reply "No, were only going to help if you do".
