Amazing how you present disagreement with your views, and pointing out their sparse foundation, as 'disrupting and shutting down discussion'. You will not find me complaining that persons expressing views contrary to mine are engaged in silencing me, or disrupting a discussion. Statements like that proceed from two things, and two things only: persons who call disagreement with themselves disruption mistake the word 'discussion' for the phrase 'echo-chamber'; persons who call disagreement with themselves 'shutting down discussion' are openly confessing themselves incapable of sustaining their views against reasoned and informed argument.
