Why should shitting on other fields or their passions be taken less seriously just because it's common for mathematicians to do it?
Neither of them genuinely dislikes the other's field/passion, they're actually very appreciative of each other's skills. It's just a very common kind of humor.
Women like R.O have contributed to all those fields since the 1980s .. but then they've been surrounded by others like C.P to take the edge off the boof heads.

Joking or ironic or not it can still be harmful.
