@Troska put it eloquently.
I understand the harmlessness of a joke, even a tasteless one at my expense.
But words have meaning and comments carry tone, especially when aggregated over years.
For adults, too. Student pilots come here to learn what kind of community we are.
Swiss cheese jokes are rare, and unlikely to cause aggregate harm. By contrast, as a woman, I bristle at something on this board pretty regularly.
I've learned to not take it personally. But only because if I did, I would be enraged most of the time.
It can be really exhausting.
That's my experience. Yours may vary.
