Moral values in liberalism and conservatism Book

Reviewers who acuse Dinesh D'Souza to be "angry" make the old mistake generations of conservatives has been made: being polite with the leftists, just to be called by them "fascists". Yes, Dinesh D'Souza is angry with leftists. I myself appreciate that. After all, politics is a war of ideas, and being polite or not is a secondary issue. On the other hand, the book explains greatly the grounds of conservatism. Criticizing the lack of scientificism in the book is missing the point: "Letters to a Young Conservative" is about a political option, so It's based on philosofical argumentation, not datas (altough there are a lot of them). Besides, trying to discuss politics in scientific bases is a kind of naive. Dinesh is an old school intelectual, not a scientist. Great book.
