What's a kid supposed to do against a concentration camp? You act like you can just disobey people when your life is at stake. Like he can just as a kid of single digit age talk anyhow he wants to people who can kill him and his family at any time. Like Kids can just be easily brave when it's naturally instinctive for kids to be fearful and dependent on others.
Unless you're suicidal or you have no concept of self preservation, that's a problem.
Bending down to the WG? He defeated his own country's king simply to save the people. Not sure how that makes him the opposite of Fisher Tiger or Hancock. He was fighting against the WG and went as far as even joining the Revolutionary army, the WG's worst enemy.
The only reason he left the Revolutionary Army and started to obey the WG was to save his only child. What father who is a good one... wouldn't put their life down for the one and only kid they love?
Kuma wasn't patient or tolerant of the WG, he just knew he had to do what they said in order to save Bonney. He refused to see her to make sure she got treated and didn't die at the age of 10 even though she meant the whole world to him.
To compare Kuma to people like Big Mom or Kaido shows you have no understanding of character. Kuma does things for the people he cares for which means he has to sacrifice.
Big Mom or Kaido don't have people they care for, so they don't need to sacrifice, therefore they can do anything that they want to do. They can go to war knowing full well people besides them will die, and that's fine with them because they're psychopaths.
To also compare Hancock along side BIg Mom or Kaido? You don't understand character. Hancock was raped by the WG. The reason she does what she does is to protect the people of Amazon Lily, so they don't get raped or go through what they went through as kids. She's no different to Kuma.
He's popular with the community because most people in the community have something called empathy (ability to put one's self in another person's situation and understand their feelings) and sympathy because they know and understand he was suffering, and you seem to lack both.
Can only conclude you didn't read Kuma's story at all, or you did and lack empathy & sympathy.
Your question makes me think if you were a family man, husband with a wife, had kids and the WG kidnapped them saying if you don't obey, they'll kill your wife and kids... since you don't understand Kuma, your choice would be to disregard the wellbeing of your family and go to war with the WG like Kaido and Big Mom would do.
To take away from reading Kuma as having a slave mentality... is wild because he didn't have one, Kuma is what any human being would ideal to become if they had the balls to do so, to be able to sacrifice yourself to people you love regardless of the consequence. He had one of the greatest mentalities in the series, and that's one of pure love - put those you love above yourself.
What's so ironic is that you bring up Fisher Tiger who actually wished he could become like Kuma, but he wasn't strong enough to do so and chose to die as someone full of hate which he resented himself for.
