No I am not
Of course you are, Fisherman. You've not been able to objectively show us there is anything call spirit. Being spiritually blind is the conclusion. You're attempting to skip over the "show it exists" part and simply claim we just can see it. That's assuming the conclusion is true in the premise.
Simply attempting to say blind people can't see red, therefore Jesus because empirical evidence shows that not only do you need to re-take that physics class, but also learn a bit about blind people and what they can do (you wouldn't imagine), learn about how to construct an argument and use critical thinking.
