(emphasis mine)The thing is, if the church meant for us to knowingly interpret those questions in a manner at odds with the way most members of the church and the leadership would define it, I don't think they'd bother with the interviews at all. Instead it would just be, "Do you think you're worthy? Ok then!" The fact that awful people can have recommends and many good people don't seems to support the idea that we should scrap or significantly truncate the interview process. But if we keep just giving our priesthood leadership the idea that we have a TBM testimony (which I think is what we do when we answer "yes" to everything), we do nothing to bring about the change that I think needs to take place, namely, letting worthiness be between the individual and the Lord. I actually think that a loving Father in Heaven and a loving Savior would want alcoholics and those who don't pay tithing and those who are in all other ways sinners to enter the temple more than anyone else. Those are the people who need to be in His presence most in order to help them repent and be healed. Jesus chose to spend his time with sinners over the pious. Why would he want his house to be different? If the questions were truly meant to be between the individual and the Lord, then why do we bother asking them?
In general, I think this is where you're most off base. I have on multiple occasions had the experience where the interviewer (bishopric and stake presidency level) has said that the last question is really the most important. One even said, without my prompting although I agree, that he thought only that question could be asked. But, as Mom said, they really have no control over the questions - and that's a good thing. There's a reason why they are instructed to ask the questions exactly as written and not ask anything else.
My bishop and SP are very well aware that my belief is nuanced. They do not know all the details of what I believe, question, doubt or don't believe. I likewise don't know those details about them or anyone else in my circle of church acquaintances although I do know some things about some people. Even here, no one here knows the full depth of by beliefs, doubts, questions or unbeliefs. I think it unfair that we cast upon them (or judge them if you will) about what they believe when we don't really know what they believe or don't believe. I do happen to know that my SP disagrees with the November gay policy - but he has never said so publicly. I also believe the assumption (judgement) is that he does fully believe in and fully support that policy.
I also believe that the WoW should not be part of the interview process, and I don't believe it is a commandment at all. I agree that God probably does want sinners to repent (i.e. change or turn toward God) and I think that's a major component of why we offer the sacrament almost weekly. I do wish there were more "sinners" at church, although I recognize we're all sinners and sometimes I don't get why those who in the Latter-day Saint perspective commit more grievous sins don't come more often and/or don't feel welcome or a part of things.
Why bother asking of the questions are between God and the individual? For one thing, how else are we supposed to do it? I am not in favor, as you seem to be, of just throwing open the temple doors. While it is possible to lie, and I have known people who have done so (and you would apparently say I lie), I do believe there needs to be a standard of belief before entering the temple. I believe that much like job evaluations, it is important sometimes we are asked to evaluate ourselves and reflect on where we are, what we're doing, and where we're headed, and while that is possible with self reflection and evaluation it is unlikely to be as thorough as being asked by someone. The same is true with countless other things, including the mundane such as driver's licenses (which I think we should be examined for more often).
Your views appear to be very black and white with no room for gray or color. The world and the church are not black and white and neither are the TR questions.
