Are there any sociology/psychology books written about 'conversation traps'? Certain subjects seem to be natural sink holes for conversation, like politics and religion. You have to be careful to let a conversation not go there, and once a conversation goes there it is impossible to back out again since it naturally escalates and people can not stop talking about it even when they want to. When you're in a cultural context that does not protect against these things being discussed with taboos it is extremely easy to let every conversation collapse into these subjects.

I want to know more about this phenomenon and someone has surely already thought about it.
