As valid as your points may be, if almost every pastor believes that the bible says X, and the bible says something that looks a lot like X, like a really sloppily-written Y, it may as well say X even if it technically doesn't. In a functional sense, the message of X (in this case, gays are bad or whatever) is still not only reinforced as message but reinforced as an explicitly Christian message. It may be that you can see clearly what the Bible was trying to say–which in its own way implies that God doesn't particularly care about whether or not his own spokespeople (which He by no means requires) are accurate or not, unfortunately–but if no other Christian figure sees it or even just if very few Christian figures see it, it is by nature unorthodox and the vast majority of humanity will go on believing that Christians are supposed to believe X and not Y.

What I'm getting at is that you may have found a linguistic loophole in a bizarre and long since outdated book of ancient Jewish law, but if nobody else is buying that your loophole is there (and this is a system where loopholes have to actively be believed to be loopholes), it's not really there, it doesn't particularly free anyone but you and a select group of others up to be gay or to get off to gay porn while also being a very specific flavor of Christian.

The very notion of reinterpreting or rewriting the Bible raises more questions than it answers, at least to me. For example, if God was truly concerned, why didn't He tell pastors otherwise Himself? It is so utterly within His capacity to do so, after all. Is it a worth thing? Is it that all those who speak for God on Earth are not worthy of receiving a minor correction to the Bible that would be a tremendous boon to very many gay people worldwide? Does God particularly care about gay people enough to save them from people engaging in violence in His name? I'm aware that it's stated in the Bible–as far as I know–that not everyone who recognizes God as God will go to heaven, that even demons must by necessity recognize him, etc, but you would think that if someone sincerely believed in Him and they were right about Him, they'd receive a distinct and clear message that parts of the very book they hold to be sacred is in fact in error, one which God could instantly fix, or even retroactively fix so that the error never occurred at all.

However, the error as of this writing still exists, which leads to the rather unsettling conclusion that the reason nothing has been done is not because God overlooked it or is trying to influence humans to change on their own, but rather that He either A) simply doesn't care or B) can't. This is the problem with all errors in the Bible, assuming that God is in fact intended to be not only perfectly capable of all things but also perfectly good. Unless God's definition of good includes allowing for the unnecessary suffering of millions of people in his own name by people using a book He inspired that contains a serious error that it would take no effort of His to fix, he either can't be perfectly good or can't be perfectly capable, one of those definitions of God must be flawed if we also take it at face value that the God of the Bible is the 'correct' God. Even if He wasn't the correct God, any system with both an omnipotent and omnibenevolent (here meaning good and not merely generous) God must answer for these same issues.
