'Parasite' is an organism which lives on a host and benefits by deriving it's nutrients. It basically drains out its host while nurishing itself and likely to leave the host in a weakened state. Sorry, I don't specifically mean to call you this despicable, awful name. I'm only trying to warn you because you are starting on a low level of earning this name. So please be careful and don't do such a hideous, indecent act. It will lead to a very disappointing and horrific end. In reality, there are people, high in rank that have rightfully earned this name and they are doomed whether it be in this life or the next. I believe God is reserving their punishments for the next world if they are living an 'eternal' happy life in this world.
EDIT: The sole purpose of any religion is to help people to become civilized. Sure it can be difficult to choose which religion is the righteous one and the best one for you since I'm going through that dilemma myself. But one can only help himself if he/she researchs. My interests are so far in Buddhism, Islam and some japanese beliefs, although they're more of cultures and traditions than to do with religion, I guess.

I'm currently focusig on Islam and its quite interesting and intriguing to be honest. It's because it has a good side somewhat different to any other religion but it also has bad side which is something that it has never experienced before, I mean especially not to this extent. Whereas, with other religions, as much as I hate to say this but they're starting to collapse and become unstable. In fact, most of them are unstable now thanks to these Illuminati and Zionist *******s. U_U Only Islam seems to be clinging on somehow, considering it's the one that is openly targeted. Very strange and bizarre, indeed.
