you really need to freshen up your debate skills man, you could have put those basic 101 complaints away easy. Also, don't argue with ignorance, IF you describe and explain to him in a rational way all of those points ( your arguments are literally the first cm of the iceberg that sank the titanic, and sound that way as well) and he still won't leave the talking points alone, then move on. People cannot be convinced out of their dogmas if they have no reason, bcuz it is driven by pure emotion, and rather than think, they will simply get angry, call names, or dig deeper into their views.
