I've posted about this exact thing before and yeah, like with all humor it's very situational. Encountering someone with a stutter can be confusing so adding a layer of jokes and self-irony is not always optimal. However it's good be able to joke and laugh about stuttering because it makes it lighter to talk about and deal with. After all, it's just stutter. I see so many people here projecting their own (legitimate) negative emotions on the recipients, imagining that people listening somehow hate them for it. I meet akward, stuttering, ugly etc people from time to time and I don't have any negative feelings towards them, it's nothing I gossip about or dwell on. We all are stuck with what we have, but we're also just NPCs in lives of others. So it's better to focus on how we feel about our stuttering and not what others might do.
