I can be wrong though but when i see religious monotheistics, i mostly seem them hating on the polytheistics,
I've seen religious monotheistic texts who aren't friendly towards them and portray them as devils (no i can't provide source about this because it's rather vague i remember this)
Recently i saw a few religious monotheistics commenting on various site like
this video makes me want to vommit. You wicked people! Turn your backs on your pagan gods.I tell you to pray to Our Father in Heaven and Jesus Christ, Our Lord. You will all go into Hell if you don't repent of your sins.
Glory, Glory, Glory be to The Father, The Son and The Holy Spirit. One God for ever and ever.
Amen.
Why do they portray them as evil? Why is monotheism better then polytheism? It's what we prefer that's the most important.
This is subjective by me ofcourse, but i think this happens quite a lot.
