That’s like saying the kid who gets the math problem right because he works out the problem correctly is the same as the kid who does incorrect math
Two kids are asked to find the square of 63.
One enters the numbers into his calculator, presses the buttons to produce the answer.
The other multiplies 66 by 60 in her head, adds 9
They both come up with the same answer.
Which one solved the problem in the "correct" way?
Did I ever say there can’t be more than one right way to get to a conclusion?
If one Christian says “I won’t read Harry Potter because my faith says have nothing to do with witchcraft” and another says “I won’t read Harry Potter because the morals they espouse are anti-Christian”, they are both right.
Further, when you are asked to prove your reasoning, it may be shown you followed sound reasoning, versus you showing you got the right answer, but not on purpose - you got lucky and got it right by accident because it’s clear you didn’t get the answer following a proper method.
