What do you mean by a talking point?
Actually, what does anyone mean by a talking point?
But you seem to be using it in a negative way.
Talking points are things you say that you've heard repeated elsewhere, usually by others who share and/or are a leader of your ideology of choice.
They are designed around their marketability, perceived or not, rather than actual facts.
So for example, if your ideology is vehemently against cheese, a talking point might be "The overconsumption of cheese has lead to the ebola outbreak", even if there is no such link between these events.
A real life example would be "How come there's still monkeys if we evolved from them?" .. The person writing or saying this did not actually read your post and is trying to reason against it with that statement. It is just something they've heard others, who share their ideology (of creationism) say. It sounds good, so they say it, but it doesn't make any sense. This will continue even in the face of "Hey, that doesn't make any sense", and so on.
That's what it means to me - if someone's essentially just repeating the position of some higher authority or some such thing - which doesn't even apply to the points made by the person they're responding to. They say it because "that's what ____ people say" rather than it actually being an actual point that they thought about and reasoned through.
I call them talking points because they exist as they are, outside of the context of a debate or discussion. They can be neatly written down and repeated ad nauseum. So for example say you have a bunch of talking points written down for the Ebola discussion. You'd go into an ebola thread, and write out your talking points, instead of actually engaging others and debating their points honestly.
