Reasoning lies against atheism, now you're just vomiting words and using faulty logic.Then they're is plenty of other reasoning tests u can apply to confirm or dismiss. For example if Islam is true why do they not tolerate other religions or atheists yet they are tolerated by other religions and atheists.
If islam is true then why should it agree with everything else out there that's false? Imagine scientists agreeing and tolerating flat earthers.
Infact id argue that islam is more truthful because it does not agree to any other ideology.
PS: islam tolerates all faiths i assumed you meant islam does not agree with them and not that islam views their believers as ppl to be killed.
PSS: also it seems like you have limited knowledge on islam ive already diagnosed your type, please refer here. Perhaps it shall serve as some form of self awakening once you understand what you are.
