I have nothing to argue with here - the stats speak for themselves. I wish that all the discourse could be based on such an honest interpretation of the data.
Yes, more white people are killed by the police than black people - the important stat, as you've highlighted is per capita. Whichever way you look at the statistics, the police and/or policing strategies are disproportionately racist in nature. I don't know how you change that but I don't think removing the police is the answer - something we previously discussed.
This isn't a one way thing either, cherry picking information happens on both sides - as Hemal Jhaveri demonstrated when she tweeted mass shootings are ALWAYS by white guys and got herself fired. Most mass shootings are done by white people for the same reason more white people get killed by the police - there are more of them.
There's no statistical link between race and mass shooting when corrected per capita in the population. Rather than come forward and acknowledge this - she retreated into an ideological 'everyone is racist against me' defence - which didn't do her credit. It was a massive own goal and afforded the political right more ammunition about loony racial prejudice on the left.
When we stick to the facts as they are, concrete and indisputable we stand some chance of maintaining civil discourse. We are then arguing about how to solve the problems (which you and I do) rather than whether the problems exist in the first place - which seems to be where a lot of the discourse is stuck.
