Welcome to the forum, Francesco! 
These are all very good and valid points! We currently have provisional Forum discussion rules where we point out that we won’t tolerate prejudiced comments and denying first-hand experiences. Asserting these rules has already led to some disputes, but we’re serious about their foundational value.
We want this to be a safe and inclusive platform and we prioritize this over members being able to do or say whatever they feel like. We’re currently working on integrating this into Community guidelines and the overall approach to moderation, so this aspect gets the importance and visibility it deserves. I hope we can publish this soon and I’m very much looking forward to everyone’s feedback then!
