Regardless of what you think, it seems that the vast majority of humans do believe in a deity which provides them with a sense of what is right and wrong. Assuming that there is a connection between belief and morality, I would expect that the vast majority are right.
All you are doing is subjectively choosing which moral code to follow.
If you believe that all moral codes are subjective, that is, not based on objective right and wrong, then you are correct. On the other hand when you say that "the vast majority of humans have a sense of right and wrong," then you must know yourself what is right and wrong.
As far as I am concerned, it seems that you are right in that people are created to love and are most fulfilled by love, but many people do not accept this. Fortunately Jesus Christ is more than religion, and more than human wisdom, and more than other institutions. Religion is not at fault for everything. Governments cause wars, businesses cheat, and criminals steal. The institutional church has done some wrong things, but it has done more things right.
To say that all religions are the same is wrong. It is a cop out for having to make a real decision between what is right and wrong.
