Not only being unfair, it shows the character and depth of the individual. People can get emotional and have strong feelings about what they believe, and that can get personal and heated with great passion. But in this case, the individual choose personal attacks in the absence of any substantial response. I don't think he could argue string theory and how it relates to Aikido. Or realize that the evolutionary model applied to any field, is still the same evolutionary model. He argued differently. But this kind of stuff he wrote really has no weight up the discussion. I just scratch my head, and think he feels defeated as a motive for his behavior while moving on.
