I'm sorry that the issue is triggering. It sounds like this is something that could be handled by a moderator as a private message type of thing. I have known that this was regularly done on a Buddhist site when members were posting opinions as if they were truths, thereby misleading and possibly harming others, especially more vulnerable members who were less experienced.

I have a pet peeve related to this issue. People think that all opinions are equal, including equally valid. But if you really think about that, it is an impossible thing. People may believe that others have an equal right to hold or state an opinion, but the validity is not automatically equal. Some are closer to the truth than others. Some are more informed than others. Some more wise from experience than others. And it isn't entirely arbitrary how such things are weighed. There are ways to verify, check, support things, even if not done afterwards.

If all opinions were equal, we would believe both that the sun went around the earth and that the earth went around the sun. How could both possibly be true or equal? Nonsense. Believing people have equal rights to free speech is entirely different from the idea that all opinions are equal. And free speech is not an absolute right anyway and never has been.
