The resolution was drafted and a vote was called on October 18th. It was called following a failed resolution at the security council which the USA vetoed on October 17th.
This is the normal speed in which the UN operates. Note that the UN Secretary General condemned Hamas with name hours after the terrorist attacks. Also note that leaving out the name of Hamas in both the Security Council resolution, and in the General Assembly resolution was on purpose as if you named one human rights violator in your condemnation, you would also have to name the other, and the draft authors thought it was likelier to pass without naming the perpetrators. The security council resolution was never going to pass because of USA complicity in the genocide, but in case of the General Assembly, they were correct. The October resolution passed, but not by as wide a margin as the later ones, e.g. if every absentee would have voted against, the resolution would have failed to get the required 2/3rds majority to pass.
“Never believe that anti-Semites are completely unaware of the absurdity of their replies. They know that their remarks are frivolous, open to challenge. But they are amusing themselves, for it is their adversary who is obliged to use words responsibly, since he believes in words. The anti-Semites have the right to play. They even like to play with discourse for, by giving ridiculous reasons, they discredit the seriousness of their interlocutors. They delight in acting in bad faith, since they seek not to persuade by sound argument but to intimidate and disconcert. If you press them too closely, they will abruptly fall silent, loftily indicating by some phrase that the time for argument is past.”
