I agree with Furman that Fembots don't make sense.

That said, I have no issue with them in my TF lore.

The Blastoff/Onslaught and Ratchet/Drift ones were the only ones that left a sour taste.


Side note:
There is a line of reasoning that every species action/reaction (and by extension, evolution/progress) is directly tied to needing to impress the opposite sex and procreate. Without either, where is the need for Cybertronian's to anything?
