People always gotta exaggerate, nobody hates on anybody that believes in himself or his sons.
It's about how you do it. Most people have some aspects of religion in their upbringing or culture, and humbleness is preached in all religions.
So when people are arrogant or narcissistic, it's expected that a lot of people won't rock with it.
As for Lavar he had his highs and his lows, only stans and haters will say that he was always wrong or right in how he moved
So you mostly agree with me then because I'm talking about the haters. And yes people get hated on all the time for being confident or assertive. Easy to frame it negatively as arrogance, aggression, etc.
No one has to like Lavar or agree with his business noves... but he's harmless and doesn't warrant the hate I've seen thrown at him.
