Did your mom clarify anything for you? I must admit the term "unconditional respect" threw me a bit also when it was first mentioned in the sermon, but I try to look at it as me choosing to show respect to another even when they don't deserve it--most especially when they don't deserve it.
I did talk it over with my mom, and went to the site-- but did not end up with the impression that they were talking about respecting men who did not deserve respect. It was more like, respect them for the things you can respect, and mention/focus on those things. However,there are boundaries, and if someone crosses the line (for example, a child molester) then you cannot and should not respect them; in fact you probably will decide not to have them as part of your life.
The FOTF site had several good articles about how much men need respect (similar to how women need love) and the details were along the lines of appreciating the good, as opposed to overlooking the good and focusing on the bad.
So my bottom line was perhaps different from yours-- and this could be attributable to not having heard the sermon directly, or it just could be a matter of interpretation. In either case, I think it's good to avoid taking for granted the things we appreciate about a partner, spouse, or anyone.... But for me, I probably fall out saying that if someone crosses certain lines, it limits the role they can play in my life--so that I can respect those who ARE in my life.
