I can't say that I dislike not being able to remove a like. Granted, some peeps do have some pretty weird likes or dislikes, but that adds to the fun of the game; they'd be a pretty boring lot if some didn't have their little quirks.

In VF2 I'll only remove a peep's dislikes if they adversely affect their work. In essence, that would be "running", "learning" or "work". I can't think of any others off the top of my head.
