A really poor way to phrase your topic if this is for school, its an inherently biased way to put it, and you're only going to get people who spend all day raging against the one side rather than an informed answer with a full understanding of both parties and their deficiencies (Because all politicians suck, it's a fact of life). The reason you're seeing people really hate liberals, is because passions are high on both sides. Half this country really hates liberals, the other half really hates conservatives. Its one way or the other, but we're equally divided on it.
Here's my quickie overview, but bear in mind the situation is much much much more complicated than this. I will try to be as unbiased as possible in describing how one group perceives the other:
Liberals are mostly disliked because they represent a platform that is 'progressive', that is they support programs aimed at helping the poor or underrepresented classes. This often leads to policies that are considered intrusive to personal privacy (Instituting a Nanny state, telling us how to live our lives because it's "good for us"), socialist (for supporting these programs with government funds rather than allowing free market to decide what's best), and are very costly. Conservatives view Liberals as bleeding heart 'takers' who spend money they didn't earn.
Conservatives are disliked because they are perceived as greedy and aggressive. Conservatives prefer the funds to go to defense rather than to social programs, believing in the free market systems to handle all of those issues. Liberals dislike this because they believe the free market system eventually only favors the rich, and without regulation we would be run by a handful of corporations (which has some precedence, look up antitrust laws from the 1920's, or The Jungle in concerns to how are food was processed and handled before the FDA). Conservatives are also disliked because they have a track record for dragging religion into an argument and making some very inappropriate remarks concerning things like rape and racial insensitivity, something Liberals vehemently believe don't belong in a rational debate. Liberals view conservative as heartless rich people who don't care about the poor because their problems don't affect the wealthy.
To be clear, neither of these views are entirely correct. As I said, it's very complex and there's never one answer to all our problems. I will suggest however, you leave your research to the books in your library, not to an internet forum. You're not going to find any help with an assignment here, only madmen screaming at monitors.
I don't like them because they are all about empowering Big Brother...they want a totalitarian system where the government runs every aspect of your life, what you eat, how you spend your money, etc. First they make people dependent on biG brother...(47 million on foodstamps) then they control you by threatening to remove your benifits if you dont' vote right
liberals want total control...thats why t hey are always screaming for more power to Big Brother, more regulations, more taxes, more oversight, more everything and anything that has big brother with his nose up your ass. Like gun control, government screams for more but nobody is suggesting that government give up its guns...oh noooooooo!
