You lost, anon, they are dead. Let them rest in peace. Why is Charizard hated? Because a group of some pokemon fanatics sought a fight with the most famous pokemon with the most fans. The most famous is Pikachu, but nobody cares about him, so the target has always been Charizard.
> Kanto starters x Charizard
> Grass and Water starters x Fire (Charizard)
> Blaziken x Charizard
> Dragonite x Charizard
> Salamence x Charizard
> Any pokemon nobody knows x Charizard
These groups always said that their pokemon was better and more popular than Charizard, but then came the megs, and TWO MEGAS for Charizard! They went mad with anger and envy.
Then Gigantamax arrived and Charizard was chosen again, that was when they realized that they lost the battle and began to beg affection for their pokemon.
But it didn't stop there, then they realized not only did their favorite pokemon lose to Charizard but they were cut from dex. They lost battle and war, and only shame and humiliation remained. That is why they are chasing Charizard, but it is no use as the number of fans is extremely larger than the number of haters.
