Why do some posters assume they have the authority to decide who, and who may not participate in these discussions?
You have the right to participate, you have the right to not to participate, you have the right and the abiliy to ignore others contribution.
But as far as I am aware, you do not have the authority to decide who can, and who can't participate.
Your claims to your physical ability to inflict violence on others is neither impressive nor of any worth on a virtual social media platform.
On a social media platform the old saying about the pen being mightier than the sword has never been more true.
