We all have heard how much social media influenced the results of the election with all the misinformation being spread so widely and easily. But there is also another factor. Social media made disrespect and insults more normative and acceptable. A great example is right here. (But it also exists on the football board, too, where an unhinged old man goes on angry rants against his perceived enemies and nobody cares.)
So if anyone wants to discuss issues without the trolls and insults, there is an alternative. One can use both boards. Just sayin'.
