Depends on who you are.
You are an Arab Muslim? You hate them for religious reasons.
Non Arab Muslim? Many have a disdain for many of the stereotypes they have and even conspiracy theories (Protocols of Zion) that exist. Some are probably true and some are not. I.e. They run Hollywood (Speilberg), they run the banks (many bank CEO's are Jews), they control money supply (Greenspan), they control foreign policy (Kissinger). Outside of those types of things, many do not like the blowback effect from the Arab world due to our support of Israel. Many attribute 9/11 to our support for the Jews. Its debatable whether this is a valid reason for Muslim anger or if it's an excuse, seeing as how Muslims have been enraged for 1400 years and we've only been a country for a little over 200. The common thought remains the same though: The US has taken a lot of heat over Israel. Many don't like this.
Many Christians simply dislike the fact they they crucuified their own prince and still "don't get it".
