This happened to me yesterday. There was a discussion thread on whether Attack on Titan is on par with great literature. I personally agreed with the sentiment and I explained in a comment, why I think so. I got downvoted because it was counter to generally accepted stance in the comment section. I was just trying to foster discussion. They didn’t even argue against my views, just downvoted me. But, I guess that is internet for you, people don’t want to have discussion. Most people are just seeking validation for their views. I am sure I am guilty of it too.
