I’ll take that as a no, you are an unrepentant open theist heretic. That, and you deny the biblical teachings of evidence of conversion and marks of false conversion. You’re in error and don’t think logically: there are sins that show one to be unconverted though professing salvation.
Reformed Theology isn’t fatalism, you’re simply showing more of your ignorance of what fatalism is and conflate it with a holy God and His ways which may well be hostility toward Him, Colossians 1:21.
Contrary to your capricious beliefs (a form of atheism) God knows every single detail of all future events, has disclosed to us the end of all things He has determined, will not be thwarted in His plan as all end according to His purpose, counsel and will exactly as He has decreed, all to His Glory, as He actually is God.
You loathe these facts and deem God unfair.
Fatalism is a metaphysical theory that all things are driven by an impersonal force. That isn’t the Reformed view. To the contrary this age is driven by God who has decreed whatsoever comes to pass, thus whatsoever He has determined as God isn’t impersonal, but is determined by a Triune Personal God who is just, holy, sovereign, kind, loving, and merciful. His determined plan is therefore not fatalism, it is all to His Glory.
