I don't want to be Analogy Police (YES I DO), but Nathan is right. This is an analogy. An analogy compares something that's substantively alike in two otherwise unalike things. An analogy does not "equate," or imply that the two compared things are substantively alike in all ways. If it did, it wouldn't be an analogy.
ANALOGY POLICE OUT, BROSEPHS.
Ya know, I almost used "compares" instead of "equates" for the post title.
OK, well he still wasn't comparing women to cows or pigs, so that wouldn't have made it much better anyway.
