Is a Muslim sinful if he does not object to the reviling of Jesus in public comments, knowing that he dislikes responding to strangers or abusive comments?

Christ, peace be upon him, is one of Allah's noble prophets and great messengers. He is among the Prophets of Firm Resolve. Whoever intentionally curses him is an apostate disbeliever, because respecting, exalting, and honoring all prophets are pillars of faith. Allah Almighty says: "The Messenger has believed in what was revealed to him from his Lord, and [so have] the believers. All of them have believed in Allah and His angels and His books and His messengers, [saying], 'We make no distinction between any of His messengers.'" So, whoever violates this has committed a grave evil, and he must be prohibited from this evil, and it must be clarified to him that it is forbidden, nay, disbelief.
