It's okay to disagree, it's not okay to call someone 'metard' or insinuate that they're not stable or gaslight them.
Let me tell you a few more things that are not okay.
A new member posts for the first time to tell us they didn't like some parts of a story. They immediately are jeered at, with mockery and contempt. That's not okay.
They are told that their short and polite message sets a world record in wrong thinking. That's not okay.
The word "toxic" is thrown around again and again by one poster. People who never used that word (not even once!!) are accused again and again by that poster of calling "toxic" this manga. That's not okay.
While others try to comment and discuss this beautiful manga, that one poster keeps derailing the discussion with messages about the perceived wrongs of other commenters. That's not okay.
The best way back to normalcy would be to stop the ad hominem arguments. And it's quite clear who started it and should be first to stop. Hopefully a mod will remedy this.
