It would be really interesting to see how this same thread would unfold if mentioning "racism" was simply not allowed.
I think you would be disappointed. I believe that nearly everyone in this thread would still find the two people who chased down an unarmed person with a vehicle, threatened him with a shotgun, and ultimately killed him when he attempted to defend himself are in the wrong and should be charged with murder.
The events in question, to me and apparently to most others, are fairly clear. The McMichaelses, regardless of their skin color, are in the wrong and are murderers. Arbery, regardless of his skin color, is a victim who was murdered by the McMichaelses.
I think you're likely the only person in this thread who feels that the actions taken by the McMichaelses are appropriate and justifiable... and I believe I'm correct in assuming that almost all of us in this thread feel that the only reason you are willing to take that view is directly driven by your own admitted views on race. That assumption is reinforced by comments you've made in this thread.
I will concede that in all likelihood, the McMichaelses did not leave their house with the express intention of killing a black guy. Most likely, they firmly believed that they were doing the right thing, trying to catch a "bad guy". I do, however, believe that their perception of Arbery as a "bad guy" is strongly influenced by racial bias. I believe that if Arbery had been white, there is extremely low probability that the McMichaelses would have armed themselves and chased him, and very likely wouldn't have considered him a threat at all. I think they would have assumed that a white kid running through the neighborhood and poking around at a construction site was just a curious kid checking it out.
Furthermore, I very strongly believe that if Arbery had been white, the McMichealses would have been arrested at the time of the confrontation, and would have been charged with murder, and an investigation launched.
You might think this is some over-sensitivity on my part. You're welcome to hold that view, although it is incorrect. I freely admit that my views are opinion, but they are also based on many observations of disparate treatment of people on the basis of race, as well as several research reports that have validly measured that disparity. It's based on the acknowledgment that black people and white people on average are measured against different expectations, and subject to different thresholds.
