> His earthly power is gone
Well... unless he has followers, right? I would argue that Jesus remains a powerful force today despite being dead for 2000 years.
I don't think people go out of their way to talk shit about everyday shitty people. It's the ones who remain influential that issue is raised.
> no tangible benefit
On the contrary, if his beliefs were especially toxic, it is extremely beneficial to speak against them. Do you really disagree?
I disagree. I say speak against the ideas, not the person, as the person dies, except Jesus who people continue to invoke his name, which probably means he transcends an idea or belief.
I have a terrible toxic belief troubles you. Can I be a member of society just because I believe pineapple on pizza is acceptable? If you associate me as a person with that belief instead of someone who believes, I suddenly become a problem, and not the belief. Jesus said to love your enemies. He also spoke against ideas, not people.
