You view eschatology from a completely different perspective than Adventists. You have adopted parts of preterist and parts of futurism, both hermeneutics being invented by Jesus in the 16th century to defeat Protestantism and divert the reformers' accusing fingers away from the papacy as being the Antichrist.
There is no harmony between the various components of your understanding. Adventists are historicist. As were the reformers. I think it would be a great idea to create another thread, although I have been down that rabbit hole before and it invariably turns into a shemozzle. Pre-trib, post-trib, pre-mil, post-mil, Amil, and all the variants in between, with no-one listening and everybody preaching and calling one another ignorant because they can't see.
Personally, I think if anyone here wants to understand Adventist eschatology, they need to study in private with distractions and all the weird opinions and extraneous confusion. I have been where you are. I was a Pentecostal for years, and Catholic before that. I understand the nuances and the vast majority of Christendom is now making plans to make peace with the Antichrist because they have forgotten and/or ignored what their predecessors taught. The reformers were right. They had the Antichrist identified, and this truth shook the world and Catholicism was being torn apart. As a result they lost their authority in civil power in Europe, and the numbers sought refuge in Protestant countries around the world, including your own. The constitution and bill of rights was written because of that history and was a protection against it happening again. Sadly, what was once an apparent mortal wound, is being healed, and the whole world will soon be wondering after the beast.
If you are interested, I can offer you some excellent Adventist sites with excellent resource material which you may download for free. You can then decide for yourself whether what we teach makes sense or not.
After another posters recommendation, I looked up Answering Adventistism. One thing I noticed straight away. While they accurately inform you of what we believe, (at least as far as I read) I noticed they didn't explain why we believe as we do. Some they write off as a result of Ellen White's visions, this is not the case. There is nothing we believe concerning doctrine that cannot be defended by scripture. That includes the investigative judgement, and the sabbath, the state of the dead, and our eschatology.
