Humiliation is relative the person and almost anything is humiliating to somebody somewhere. Some people may find being naked with a man on top of you humilating (why did people use to wear nightgowns during lovemaking) but would you therefore conclude vanilla sex is humiliating.

In bygone days one of the purposes of a public flogging was no doubt humiliation but when the masochist is whipped in front of a crowd at the local bdsm club he/she may love being the star of the show and centre of attraction.

Yes almost any activity (bdsm or otherwise) can be done in such a way that the bottom finds it humiliating but to say "most all acts involved in BDSM have roots, small or large, in Humiliation" implies they are a derivative or sub class of humilation.
