There's a lot of actual prejudices (not just banter) among, say, "educated" tech industry workers, too.
Including sexism, racism, ageism, and classism.
Most people will at least superficially hide it in modern workplaces, but it's still there, and having effects.
You've probably seen evidence of this places you've worked, and you can also see it often in pseudonymous HN comments.
You don't even need to be inappropriate to have workplace banter. Nobody ever said that a light environment has to be built on jokes that bust chops. In fact, busting chops kind of blows. There's plenty of room for clowning around outside of that, and plenty of ways to build camaraderie, too. You don't have to bring racism or sexism to the table to have a good time, and you don't have to have a good time at someone else's expense.
Man, I'm really sick of the robotic culture of tech. It's such a stuffy bummer. We should be making more skeleton jokes and showing each other macaroni art pictures.
Professionalism is to keep distance to others, banter is the opposite, as it is a form of bonding.
"Modern" workplaces that advertise themselves as such are very likely toxic. Might seem counter intuitive but it is often the case in reality.
