Hi friend. There's two ways to compare things together, using either a simile or metaphor. A simile uses "like" in the sentence to compare two things: hot dogs are like sandwichs. A metaphor is symbolic of something else, commonly also called hyperbolic communication: Elon needs to pull his head out of his ass.

What we have here is called a statement of fact. It is not a comparison to say that I've had both good days and bad days at my work. Do they have the same context (work)? Yes, but most people would compare their good days to other good days, and their bad days to other bad days. What I responded to is called a non-unique argument: i hope this is self explanatory. It is disengenuinous to say that jokes do not cause harm, when there are many types of jokes lead to additional harm through the normalization of stereotypes and rhetoric. In this case, the original commenter called out a joke that could potentially lead to harm

Hope this helped ❤️
