Good reading????????

I was just browsing Amazon's Kindle books under the topic Political Ideology.  I must admit I was looking for some interesting books to read on liberalism and liberal politics.  How many did I find?  Not many at all.  Just a few books that might be of interest.  However,  I must report that for every book that may in fact be pro liberal, there are at least 15 anti liberal right wing books.  What does this tell me????  It tells me that liberalism is hard to defeat.   It tells me that right wing ideologists are busy creating work after work to convince the public that liberal political theory and liberal philosophy are "evil, wrong and backwards".  Does this convince anyone?  Give me a break.  It seems that if you want to be a good right wing conservative, you better invest in a lot of reading.... you're going to need it!!!!!!!  
On the flip side, political cartoons are 80% liberal.  A simple message.  A drawing and a little bit of commentary.  Simple.  Easy to get the liberal philosophy.... A Ph.D. like project to try to fight liberalism.
Ok, I have not yet found the great liberal thinkers book.  But I do have 4 of Anne Coulters books that I plan to visit to discover the great conservative arguments.   Where do I lie?  I must admit that my thoughts are that liberalism is the way our society progresses and that our future is based.
