>Why weren't Jesus and the Apostles clearer on some stuff?
It is clear.
Some other things that the Lord was also perfectly clear about, however, are:
<that people would ignore His message
<that the world would hate Him and His followers
<that many would come and try to corrupt and deceive His followers, even posing as false Christs
<that countless souls would be lost through their resistance to the truth
<that only a few would actually make it to Heaven
The Apostles are also crystal clear, too, especially when you remember that most of the epistles show the Apostles trying to firefight heresy and heal divisions in the nascent Church.
Complaining about the Bible for this kind of thing is a small step removed from the "Why doesn't the Bible completely conform to my enlightened, post modern 21st century political preferences?".
>Humans are pure scum
>these shitty people
This is a terrible attitude to have. I think you should be more concerned about your attitude to others than the sins of others.
