Could instead of having pro and con people write their argument for the question without putting it as pro or con. Then people can vote where they value the argument morally or for other reason on a 10 scale or something like that. Example: Issue - WiFi should be controlled fully by the WiFi alliance(something like that) Argument - WiFi use unlicensed spectrum (This could be seen both as positive and negative)

So then people vote if they think its more positive or negative by rating it from pro to con on a 10 scale. But if there are sub arguments to the arguments the voting of the sub arguments affect the value of the argument. Sub argument - non-licensed WiFi create a market for cheap electronic equipment connected to the cloud(iot). (Could also been seen as pro or con.) And so on.

Maybe bad example, but if a argument should support a thesis or not, I think is good to put in the hands of the peolpe with their values instead by the writer of the argument. And as all is not is not black and white a 10 scale (something similar)could make it more colourful and maybe more accurate to what people think.
