Here we go. One adult telling another via the internet to grow up. Awesome way to make an argument.
We call him a point fighter because he started his career fighting semi-contact kickboxing or otherwise commonly known as point-fighting. This has nothing and I mean nothing to do with his finish rate in MMA or other combat sports for that matter. He could have a 100% KO rate and he would still be a point fighter by origin. What you're thinking of is called a decision fighter. You may use those terms interchangeably but point fighting really is a discipline just like wrestling is a discipline.
The sole qualifying criterium for being a point fighter is having participated in a semi-contact or point-fight. It's rather trivial really.
