What are two minutes hate and hate week?

They are pretty much what the title suggests;there is a whole lot of hate going on! The hate is distributed against Goldstein, Oceania's Jewish version of Osama bin Laden, any the enemy of the moment which Oceania happens to be at war with. People scream, yell, throw things at screens and basically have an intense hate session. The week of hate is more organized, kind of like a "hate-apalooza".
