Fusion - I have some sympathy for the thought behind your post. Whatever the faults of the WTS there is little to be gained from throwing logical fallacies back at someone trying to argue for the WTS.
Having said that, a objective analysis of what exactly the WTS changes and how they change it shows time after time after time that they apologise for very little, make zero mention of how 180 degree turns in doctrine makes a mockery of their assertion that they have the "truth" and expect the flock to simply follow without comment.
On top of this, they refuse to address glaring holes in eschatology such as the 607 date, the generation teaching, glaring inconsistencies in the blood doctrine and child protection issues. Not only is dissent managed by demonising and excluding perpetrators but even honest hearted questioning and discussion is prevented through thinly veiled social manipulation.
The fact is that there is always a hidden agenda to any action the WTS undertakes. They don't wake up one day and go "oh we were morons about this" and change it, every action is carefully planned and thought out. They lay the groundwork for changes months, even years in advance. Even the GB approval process requires ALL to be in agreement.
If you think the change to the types/anti-types understanding is simply them thinking they went to far in the past then think again. They are making things less specific because firstly it means they can be held less accountable when things don't add up and also, I believe, to make future arguments that other scriptures are to be taken less literally more palatable. I think they have a long term plan to reduce the specific nature of certain prophesies such as the generation teaching and the only way of doing this is getting rid of loads of cases where the hubris of Freddy F and his minions got the better of them.
So, when you are faced with a torrent of "apostates" biting back at you over things like your OP then just bear in mind many on this board have seen the two faced and self-serving nature of the GB and WTS at first hand over and over again. The WTS is far less genuine and honest heartedly misguided than you would like to think.
