1 Kings 18:27 At noon Elijah began to taunt them. “Shout louder!” he said. “Surely he is a god! Perhaps he is deep in thought,
or busy, or traveling. Maybe he is sleeping and must be awakened.” 28 So they shouted louder and slashed themselves with swords and spears, as was their custom, until their blood flowed. 29 Midday passed, and they continued their frantic prophesying until the time for the evening sacrifice. But there was no response, no one answered, no one paid attention.
What did Elijah mean by 'busy'?
1 Kings
....However, Elijah refused to acknowledge that Baal was a god at all. He suggested that Baal might be "occupied" (v. 27; lit. relieving himself)...
And in Galatians, Paul suggests that whoever wants to be circumcised should castrate themselves. Is that not a mockery?
Ah, let's look and see enough to have a sense of what is happening and what the words refer to --
22Then Elijah said to them, “I am the only one of the Lord’s prophets left, but Baal has four hundred and fifty prophets.
23Get two bulls for us. Let Baal’s prophets choose one for themselves, and let them cut it into pieces and put it on the wood but not set fire to it. I will prepare the other bull and put it on the wood but not set fire to it.
24Then you call on the name of your god, and I will call on the name of the Lord. The god who answers by fire—he is God.”
Then all the people said, “What you say is good.”
25Elijah said to the prophets of Baal, “Choose one of the bulls and prepare it first, since there are so many of you. Call on the name of your god, but do not light the fire.”
26So they took the bull given them and prepared it.
Then they called on the name of Baal from morning till noon. “Baal, answer us!” they shouted. But there was no response; no one answered. And they danced around the altar they had made.
27At noon Elijah began to taunt them. “Shout louder!” he said. “Surely he is a god! Perhaps he is deep in thought, or busy, or traveling. Maybe he is sleeping and must be awakened.”
28So they shouted louder and slashed themselves with swords and spears, as was their custom, until their blood flowed.
29Midday passed, and they continued their frantic prophesying until the time for the evening sacrifice. But there was no response, no one answered, no one paid attention. ..."

What is Elijah highlighting here? He is showing the emptiness in the expectation that an idol can answer.
He is not mocking an individual we can see, but mocking a belief in an idol.
We can indeed criticize and show the wrongness in ideas, things, actions, doctrines, notions, theories, etc., etc., etc.
None of those is mocking a person.
A person isn't their idea. The idea a person has isn't the person themselves.
You and I could indeed criticize an idea, or show an idea to be empty, wrong, etc...
If you mock a person themselves that's a very different thing.
