Good post.
I think the biggest problem in modern debates is the basic ratios,
2 x ears 1 x mouth
Most won't even listen to the opposing 'facts' or 'points' of debate.

And whenever a 'reasonable' / logical point is raised the default position is to "play the man rather than the ball" ie shoot the messenger, call them names or similar.

It is disappointing to see & hear people lower themselves to this level of 'debate' rather than good argument, considered opinion, and maybe a willingness to change position, or at least contemplate it!

In some ways it reduces the "human" to an "animal-istic" level
a fight or flight situation rather than intelligent discussion.
