How do you know what you feel is right? Haven't your feelings ever turned out to be wrong? Are you are saying that what you feel determines truth? If so, then you are putting yourself in the place of God, and looking to yourself for what you "feel" is right.
If religion is whatever you feel is right, then that could lead to chaos. What if some people had a religion where they felt stealing was acceptable? And what about lying and cheating? Would you trust someone who believed in a religion that felt it was all right to steal, lie, and cheat?
Hitler felt killing Jews was right. He was wrong. The Bible says that the heart is deceitful and untrustworthy (Jer. 17:9). If you could come to know truth by what you felt, then the Bible, which is the revelation of God, didn't need to be written. But it has been written, and it has revealed that only God is the Source of truth, not your feelings.
I've never known truth to contradict itself. What if someone felt that something was right, and another person felt it was wrong? Would they both be right? If your statement is true, then how could there be a contradiction like that, if feelings determined truth?
