I don't know if you have.
And anyway, it's irrelevant to my point. Democracy, and freedom of speech and thought is not in the gift of you or anyone else on this forum; in this country it's a given.
At the moment there is no official determination of cause. So human beings speculate. This is a discussion forum. I see no conceivable reason, beyond libellous or illegal posts, why anyone would want to attempt to stymie any or all discussion however well, or otherwise, informed it may be?
You'll again note I don't include 'upset' to anyone in the above catagory. Neither you, nor me, nor anyone has the 'right' to go through their lives and not be offended.
This is not meant to single you out in any way, I'm just responding, publicly, to your query.
Thanks again.
