Chiki probably has an MBTI personality type of ISTJ - people with this type tend to think that they are always right. Often times, they are since they usually give their own arguments due diligence. Social skills don't come naturally though for these types, and I doubt he has ever really faced the reality that sometimes your beliefs are not entirely correct. In the case of speed runs, he's pretty much started from the premise that LTC is the true way to play, and will aggressively fight anyone who thinks otherwise. It's not that this trait is inherently bad - these types are great at getting things done correctly and by the book, but when they are undeveloped socially as well as intellectually immature, they limit themselves to much to only what they understand and shut down too easily that which they don't. Obviously other people aren't really helping this problem - many just want to prove to him that they are right too even though it doesn't accomplish anything because the ISTJ is "always right"
Of course I could be completely off base, and he might be a similar judging type, but reading this page may be illuminating to understanding him better and how he can identify and strengthen his weaknesses. http://www.personalitypage.com/html/ISTJ_per.html
Anyways, I encourage everyone to find out their own MBTI personality type, as understanding yourself and others is really important if you care about having more effective relationships with others, and getting things done.
