Your thought process is all wrong. Your comment has to much "I" and "ME". You say you don't know what the Bible says about tithing, so why not stop there? God gives us everything we have, so shouldn't it be your utmost obligation to find out how to USE what HE has given you?
Another thing to consider: Who else is going to pay salary for those men pastoring? Just going to let everyone else pay your pastor to shepherd his flock, you included?
