Opinion pieces liven up a site. They’re interesting, and allow people to spout off about stuff, throwing out ideas and concepts that may or may not be correct or fair.
They can be a good starting point for people (the author or just readers) to then go and write a proper article on some related topic, with proper research and diligence.
They can reveal a lot to the inexperienced reader about particular topics, giving a “flavour” of what is going on in those areas, without the reader having to first learn and understand all the mechanics themself.
But…sooner or later there will be some that are “rant-tastic!” as a friend of mine puts it.
Note: Moderation would not go beyond removal of hate speech etc and anything that veers close to libel or any such. Perhaps we could add “other links that might give opposing opinions” at the end of each piece (if any editor could find any!).
