Yeah, when people like kawaii, assume your beliefs are the spawn of the devil, it's kinda hard to find any ground for serious discussion. It's times like that to "shake the dust from your sandals" and move on. (Mark 6:11)
Sincerely
Matthew 12:31-32,
Therefore I say to you, every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will not be forgiven men. Anyone who speaks a word against the Son of Man, it will be forgiven him; but whoever speaks against the Holy Spirit, it will not be forgiven him, either in this age or in the age to come"
