Thank you to those few of you who have made a genuine effort to answer my query about posting elsewhere on the internet.
I'm sad to hear your experiences were instant bans (obviously, I've no way to tell if that's true or not, so have to take what you're saying in good faith). That is not the outcome I'd have preferred for you. The preferred outcome, obviously, would be to have left those threads active and allow debate to flourish...
...which segues neatly to the next point, since I can already predict the reactions of many of the less capable regulars here to this post.
There has been much reference to Reddit. Not just on this thread, but I've seen it constantly and consistently used in weaponised whataboutery across this area of MN ("yeahbutyeahbutyeahbut Reddit", "Reddit are worse times ten", "At least we're not Reddit", etc.).
Unfortunately, this is not quite the 'gotcha' some of you seem to think it is, so I'll state here and now, very plainly for the slower children at the back, nobody - absolutely nobody - is suggesting Reddit is a bastion of balanced, informed discourse. Indeed, it's often worse than this particular area of MN, but the salient point here is that you are both cut from the exact same cloth.
I close as I opened, by saying again that it's unfortunate that those who did attempt to post elsewhere had their posts/threads/accounts/whatever banned for doing so; I imagine it unfortunately only reinforces the pervading, obsessive attitude here that anything not MN - and Reddit especially - is evil, or misguided, or beyond the enlightenment some of you genuinely seem to think you've achieved.
Again, that pesky cult parallel...
