Exactly.
but, as I said, it's extremely subjective, and should not be dealt with in a general way, but rather broken down into subcategories, like "religion criticism", "radical feminism", "men's rights", etc, whatever ruffles people's feathers these days.
Unless you have some reason to think that a non-insignificant number of advertisers would be OK with ads on a subset of those categories but not all, that's just pointless busywork.
