Along the course, the opinion generates counter opinions, that further the discussion of the topic so that for all readers, all sides of the issues are conveyed to allow a bystander to make an informed decision.
As long as the opinion has some minimal foundation for it, all contributions are welcome provided we respect the individual and not make false accusations. We must choose our wording with the utmost care.
