There are rules you know. Just as there are rules in MATH so too are there rules in LOGIC. Logic SHOULD BE one-size-fits all. The rules don't change to fit the beliefs or dogma or propaganda. Theoretically.
Every single person believes he/she is logical. So I guess then logic is mutable and not fixed.
Both things can't be true. A thing cannot be mutable and also immutable simultaneously can it? What about sequentially? How?
