I say leave it open, you can’t “un-mod” it because it’s on a public forum and there are some folks that like entertaining themselves on it.
Also, if it was closed those forum members would take the argument to new/other threads and the forum would end up being cluttered with multiple same topic threads.
Also, despite the bickering in there, the topic is important to all. Some of the posters are both passionate and informed on thier point of view, you might not like what they have to say but let them speak. This leads me to believe that intelligent conversations on such divisive a subject should continue, with the obvious moderation considerations. (Sorry Mods)
Warnings have been issued and communicated, let the posters in there decide whether they want to follow the directive or not.
I vote to remain it being open 😆
