Can someone explain this?

Could someone please explain why my post #65 (which has been replaced by something else) was deleted from the Zapatista Army of National Liberation PDF? It was under the thread "Should you stay in or end an affair?" and read: "No. People have learned how to act civilized, and if they start acting like pigs, I'm out."
My vocabulary might be a bit blunt, but I wasn't insulting anyone personally; I was simply expressing my disagreement with the behavior being discussed in the topic.

No explanation provided?

Yeah, his language was definitely "sharper" than it needed to be, and honestly, it felt totally uncalled for. In that specific moment, there wasn't anything positive he could have contributed to the conversation; it was all just unnecessary noise.
