I am really souring on such conversations because of the tremendous number of bad-faith arguing tactics people use -- willfully misconstruing your point, racing as quickly as possible to a glib dismissal without really understanding what you said, or, like you said, link-bombing. Another failure mode I find extremely frustrating is failure to understand analogies. For instance, if I were having a discussion about whether potatoes are healthy it might go like this:

A: Of course potatoes are healthy! They're natural!

B: If everything natural were healthy it'd be healthy to eat hemlock.

A: Potatoes aren't hemlock and it's really offensive you'd make that comparison.
