We absolutely don't think Imzy should be a place where people can only say nice things and anything negative gets removed. That defeats the point of talking at all.
Our vision is that communities enrich people's lives in a positive way. That doesn't mean every comment, post, or discussion is positive. It means that I come away a better, more informed person from the discussions I have, or maybe I just enjoy my time there.
What that means is that harassment that makes people unhappy, fear for their lives, or feel like they can't participate isn't okay. But disagreement and even voicing opinions that are very unfavorable can still exist. We all become better people when we can share our own perspectives and hear the perspectives of others. Otherwise you end up with an echo chamber.
Hope that helps explain our thinking. I'm happy to elaborate further if you have any questions.
