If you think it merits discussion and your discussion is merely some opinion that doesn’t cross any of the site guidelines (sums to “I don’t care about this topic much so you shouldn’t either”), then there’s no basis for flagging it. Flagging means it’s either off topic, inflammatory, or not worthy of discussion. It’s on topic, and obviously not inflammatory. So you’re left with worthy of discussion... and you obviously are discussing it. Put it this way: if this is worthy of a flag, why are you here giving soft opinion as to why you personally would ignore it, as opposed to arguing why it shouldn’t be allowed period?
