"minors" and "kids" are also not necessarily the same. Talking about 16-year-old wearers and 11-year-old wearers is very different. I would consider both uses rather questionable, and would say we should not promote either, but putting a belt on an 11-year-old is way more wrong by orders of magnitude.
Also, huge difference between supporting keyholders and supporting wearers. I am pretty sure every time a 13-year-old posts about having been locked without release for years, that is just a crazy person's stupid fantasy, but something about a 17-year-old who can only take off her belt while under her mother's watchful eye is not so far from the truth that she cannot at least be given the benefit of doubt, and she should have access to information about things like her legal rights, emotional support from other people and stategies that allow her to live a happy life within her restrictions if the does not want to fight for her rights.
On the other hand, if someone says he is a dad who wants to lock up his precious princess so she does not spoil her value as a virgin, eff that guy.
