Its really strange to me that you would advocate the idea that we should parrot bad points to propagandize our perspective. I don't mean this as insult, I just find that a really alien way to look at the world...
As a counterpoint to some of what I understand your stance to be, in my experience those kinds of hollow arguments tend to only appeal to people who already generally agree with them. To my mind, that makes them much more effective at polarizing perspectives than actually informing anyone's perspective in a meaningful way. They ensure that people who have been consuming intellectually bankrupt reinforcements of whatever they already believed are even more incapable of meaningfully engaging with people they don't see eye to eye with, when that opportunity arises
I understand that the popular, cathartic, take is that we should just hate the bad people who think the wrong thing and that talking with them is a pointless waste of time, but in my experience the only thing that ever seems to change individual perspectives is compassion and sincerity, perhaps especially when not entirely deserved. And I also find that dismissing the intellect or emotional capacity of anyone I disagree with as a means to justify hating them and what I've decided they represent is a really toxic way to engage with the world. And by that I mean toxic to myself- I think its toxic to others too, but frankly writing off half of my country folk as stupid wastes of oxygen we'd all be better without feels poisonous to my own emotional wellbeing.
Do with that what you will 🤷
Edit: some wording.
I don't even necessarily disagree with your point that convincing people who are only going to engage superficially is politically important at scale, and that those people may at times be more swayed by hollow talking points than well reasoned arguments, its just very foreign to how I'm used to relating to the world I guess
