This applies to everything but imma talk about the DB community.
Certain fans choose to go against logic because the internal emotional response is more gratifying for them. Examples would be...
"Gohan is weak because he isn't murderous anymore."
"Piccolo is Gohan's real father."
"Chi-Chi is the worst mom."
"Vegeta is the best father."
"18 doesn't love Krillin."
"Yamcha cheated on Bulma."
These are emotional responses to justify what they want or wish was true. Now here's the facts...
Goku spent more time with Gohan than Vegeta did with Trunks. Goku has died for Gohan twice. He tries to spend as much time as he can with his sons when he isn't dead. Too many examples that Goku is a good father.
Gohan has controlled his rage & gained more power & confidence. A calm mind and confidence allows for better control of his power and better understanding so he can keep improving.
Piccolo's more of a brother to Gohan that went from cruel to kind. Ppl ignore that Piccolo abused Gohan at first when he was still evil. Goku never abused his sons.
Krillin's the most courageous character 'cause bravery in the face of fear is courage. Krillin is often not strong enough to defeat the enemy, yet he does everything in his power to help and save others. Gohan is a lot like Krillin, except Gohan has Saiyan blood so he is able to overpower his enemies.
Chi-Chi is a loving mother who wanted to keep her child safe when young Gohan was forced to fight murderous adults. She helped Gohan achieve his dream of becoming a scholar. She even saw the importance of fighting after Goku died and she trained Goten how to fight. A wonderful mother.
Best DB fathers are Gohan & Krillin. I would say that Goku is right after them. The more human characters make better fathers because they don't have Saiyan traits. Vegeta was a terrible father that developed into a decent parent once he became more "human." (Stop taking his development away Vegeta "fans")
There's too much evidence to show how much 18 loves Krillin! I would be here all day if I covered allof it. But, there's the story of DBFZ in which 18 & Krillin were constantly concerned for each other, the fact 18 found Krillin attractive first & kissed him, 18 thinks Krillin is cool (she says so herself), & the fact 18 mentions her days are filled with happiness of being with Krillin & Marron, ect.
More evidence shows that Bulma would be more likely to cheat. Depending on your definition, she has "cheated" (emotionally). Toriyama said that Yamcha is still nervous around women and even lost a job because of his phobia. Realistically, they just broke up again. Then, Bulma made her mistake with Vegeta & lied to Trunks to make him think better of his parents.
People who are mainly led by their emotions usually refuse to admit or believe fact & logic, because it doesn't give them a feeling of superiority. Or they would rather believe lies than believe truth (applies to many ppl). Lies give emotional responses that validate these ppl. Makes sense.
The opposite are the "logical" ppl. These ppl are actually led by a balance of logic & emotion. They see the truth for what it is & accept it while being able to have the emotional reaction within themselves that they desire. "Logical" ppl can acknowledge flaws in the characters they like, while "emotional" ppl deny the obvious flaws.
Emotions are responsive to logic. Meaning that "emotional" ppl have flawed logic, while "logical" ppl have emotions that reflect accurate thinking. Emotions aren't bad to have.
Applying this to the DB fandom would be like this...
EMOTIONAL: "Chi-Chi should DIE! I want Goku to be with Bulma instead, so I'm going to spread lies about Chi-Chi for validation."
LOGICAL: "No, Vegeta is not the kindest guy, but he did develop a lot. Don't spread lies."
I find it hilarious (& sad) how so many ppl enjoy being wrong & want others to be wrong with them. I guess misery does love company.
And the Emotionally Logical ppl are the ones that are looked down upon by most of the fandom? Interesting.
