Countering hate comments? Where? Because I must've missed them. All I've seen is page after page of people explaining why Hebikawa is actually the most fascinating, tragic, and well-written character in the series.
You wrote a whole psychological breakdown to justify her behavior. Sure, she has a sad backstory, but you're acting like you're standing up to a crowd of haters when that crowd barely exists. If anything, the actual unpopular opinion here is saying, "Maybe using someone to hurt an innocent person isn't exactly okay," and then getting dogpiled for it.
This isn't really pushing back against hate. It's just another "my problematic oshi has layers" post. You're piling onto the consensus, not pushing back against it.
