I don't hate them.
Adventists believe Jesus is the archangel Michael. Which is not scriptural. Whether they are a cult or not I don't know.
This is not accurate -
Adventists believe in the Trinity. God the Son is incarnate as the Son of God - Jesus Christ on earth. But as we see in Genesis 18 and 19 God and the angels can "appear" in the form of a man if they so choose. What is more God the Son can appear in the form of the archangel Michael for His own purposes. God has angels and Satan in rebellion has his fallen angels - Angels either hold their allegiance to God or to Satan. But in Revelation 12 the Angels faithful to God - who serve God are said to be in the group "Michael and HiS Angels" and in Hebrews 1 God says "Let all the Angels of God worship him" they serve God the Son. Who appears in the form of Michael in their ranks as the "Archangel" the head of them all. It is a "form" he takes not - but not an incarnation.
in Genesis 18
18 Now the LORD (YHWH) appeared to him by the oaks of Mamre, while he was sitting at the tent door in the heat of the day. 2 When he lifted up his eyes and looked, behold,
three men were standing opposite him; and when he saw
them, he ran from the tent door to meet them and bowed himself to the earth,...
16
Then the men rose up from there, and looked down toward Sodom; and Abraham was walking with them to send them off. 17 The LORD (YHWH) said, “Shall I hide from Abraham what I am about to do, 18 since Abraham will surely become a great and mighty nation, and in him all the nations of the earth will be blessed? 19 For I have chosen him, so that he may command his children and his household after him to keep the way of the LORD by doing righteousness and justice, so that the Lord may bring upon Abraham what He has spoken about him.” 20 And the LORD said, “The outcry of Sodom and Gomorrah is indeed great, and their sin is exceedingly grave. 21 I will go down now, and see if they have done entirely according to its outcry, which has come to Me; and if not, I will know.”
22
Then the men turned away from there and went toward Sodom, while Abraham was still standing before the LORD
Genesis 19
Now the two angels came to Sodom in the evening as Lot was sitting in the gate of Sodom. When Lot saw
them, he rose to meet them and bowed down
with his face to the ground.
@EastCoastRemnant and several others indicate they do not.
Individuals here and there may claim whatever they wish - but when talking about a denomination if you want to know what the church actually teaches look at its statement of faith. Seventh-day Adventists have an official voted statement of beliefs - voted by the entire world church - with representatives from all over the world coming together every 5 years to review and confirm or change-if-needed their statement of beliefs.

Trinity (Fundamental Belief 2)
There is
one God: Father, Son, and Holy Spirit, a unity of
three co-eternal Persons. God is immortal, all-powerful, all-knowing, above all, and ever present. He is infinite and beyond human comprehension, yet known through His self-revelation. He is forever worthy of worship, adoration, and service by the whole creation. (Deut. 6:4;
Matt. 28:19; 2 Cor. 13:14; Eph. 4:4-6; 1 Peter 1:2; 1 Tim. 1:17; Rev. 14:7.) 1 John 5:7-10 KJV
Mark 12:29-30

And eastcoastRemnant will admit to this - the Adventist church - as a denomination believes exactly what you find there - the Trinity.
I myself might choose to have some odd idea or two - but I cannot in all honesty claim that whatever off the wall thing I happen to choose - is in fact the actual beliefs of the SDA denomination. For that you have to go to the actual voted statement of beliefs.
I think you are incorrect, thinking that God the Son appeared in the form of the archangel Michael. Where does it say that in scripture
The 3 men in Genesis 18 turn out in Genesis 19 to be two angels - plus God.
And "scripture does say 3 men" in Genesis 18 for God and the two angels.
But as we all know - that does not mean God or angels either one - are really just "men".
---------------- so then "Michael your prince" - the "prince of your people"
Isaiah 9 -- the ONLY prince from heaven - given to us in all of scripture
For a child will be
born to us, a son will be given to us;
And the government will rest on His shoulders;
And His name will be called Wonderful Counselor, Mighty God,
Eternal Father,
Prince of Peace.
Dan 10
21 However, I will tell you what is inscribed in the writing of truth. Yet there is no one who stands firmly with me against these forces except Michael your prince.
We have only one prince in heaven as Isaiah 9 points out - it is Christ and in Dan 10 it is the name Michael that he is given.
And of course God the Son (and not some angel) is the head of all Angels
Hebrews 1 -
6 And when He again brings the firstborn into the world, He says,
“And let all the angels of God worship Him.”
Rev 12
7 And there was war in heaven, Michael and His angels waging war with the dragon. The dragon and his angels waged war, 8 and they were not strong enough, and there was no longer a place found for them in heaven.
