While I haven’t seen the previous conversation, looking at the title of this post and also at the title of the community, that leads me to believe that this may not be a community for political history.

Since many historical events (especially in regards to politics) may be controversial, painful, horrendously offensive, stressful or annoying, that leads me to believe some people might have gotten pissed off reading that stuff in this particular community.

That is my best guess.
