Another example of it right here.
For simplicity, I'll summarize the findings of the articles posted earlier.
74% of extremist acts of violence in the US have been found to been at the hands of right wing ideology. 24% is apolitical (example, Vegas shooter, looting in Ferguson MO) and 2% at the hands of left wing ideology.
Findings show that 93% of BLM protests have been peaceful. Trump's own DHS stated right wing extremism is also the most dangerous threat in the US as of 2020.
Therefore, a simple mathematical application would mean that of the 7% non peaceful BLM protests, 74% of the violence that occurred would have been at the hands of right wingers. The couple dozen articles I posted listing names, charges, etc support this. Yes, there has been some left wing violence but it's statistically insignificant.
People who deny this simple but logical and accurate statement that right wingers are responsible for most of the violence at BLM gatherings are either willfully ignorant about it, or support it. Neither outcome looks good for their moral character or intellect.
