I don't think it's unreasonable to assume that the vast majority of the incidents in their compilation came from reports to their website, and that media accounts were likely a small percentage.

Therefore, I don't think it's unreasonable to conclude that the very nature of the method of data collection skews the results.
I don't doubt or dispute that racists/nationalists have been emboldened by Trump's election. But it's also valid to point out that just because that chart was published by Forbes doesn't make it accurate scientific research.
