My question was why one should believe that? I have no reason to believe that, so I don't.
Christians that are hated are hated for their opinions and actions. You and others have been told that repeatedly in a thread asking why Christians are hated and none have showed any evidence that they even read the answers.
The Jews would have executed Jesus themselves if they had been sovereign. And the Romans didn't execute people because the Jews asked them to. He committed a capital crime by their reckoning. Interestingly, the Romans agreed, but cited a different capital crime. Jesus was executed for violating Roman law, not Jewish law.
That's incorrect. They do, and it's one reason that some of them and their religion are disesteemed by many. In America, they're very much trying to interfere in the lives of LGBTQ+ and pregnant women who want an abortion on moral grounds. They would do the same to me, an atheist, if they could. The Christian Bible goes to great lengths to marginalize and demonize atheists. Earlier on this thread, I posted this. Why don't you take a moment to read that and explain why you don't think that is moralizing against unbeliers, and moreover, why you say that it isn't bigotry and hate speech if you think it's not:
[1] "The fool says in his heart,'There is no God.' They are corrupt, their deeds are vile; there is no one who does good" - Psalm 14:1
[2] "But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, all liars, shall have their part in the lake which burneth with fire and brimstone." - Revelation 21:8
[3]"Do not be yoked together with unbelievers. For what do righteousness and wickedness have in common? Or what fellowship can light have with darkness?"- 2 Corinthians 6:14
[4] Who is the liar? It is the man who denies that Jesus is the Christ." - 1 John 2:22
[5] "Whoever is not with me is against me" - Luke 11:23
Altogether, they depict unbelievers as corrupt, vile, wicked, abominable, godless vessels of darkness in the service of evil, not one of which does any good, to be shunned, fit to be burned alive forever as enemies of a good god, and the moral equivalent of murderers and whoremongers. Isn't that reason enough to disrespect the religion that teaches people to think and say such things?
Try substituting Christian (or gay or black) for unbeliever in those scriptures and tell me if you consider that anti-Christian bigotry: The fool says there's a god, but such people are vile and corrupt, not one of which does good. Not one. How about you? Are you a good man? You're slandering an entire class of law-abiding people who are typically gainfully employed, raise families, and contribute to their communities with a lie which you have assimilated uncritically. Does a good man do that? Dopes a religion that teaches that deserve the unbeliever's respect or his contempt?
Sure it is. Somebody has just stricken your cheek. What are your options? You can hit him back. You can cover your face. You can walk away. You can try to negotiate a peace. Or, you can give him the other cheek to smite. Offering the other cheek is not a good choice.
Turning the other cheek is not self-defense.
And if one is trying to make some statement of tolerance or non-violence with this act, shouldn't he be offering the tender cheek? Turning the other cheek is not even as good as offering the same cheek, and both are at the bottom of any list except that of a pacifist, who would disagree with you that there is nothing wrong with self-defense and put striking back at the bottom.
