I'm afraid that I'm too easily offended by those who choose to be easily offended :)
Seriously, we're grown-ups so we get to choose when we're going to be offended, and names and vocabulary should be seen as just that. The term 'feminized' is, like any other, far too ambiguous in actual use to serve perfectly or to cause unnecessary offense. If you'd like a different term, use it but don't fret about vocabulary that works well for others.
For what it's worth, I don't care for the term either since I've seen it misused too often. But I'm willing to give others the benefit of the doubt when they choose to use it.
