Welcome to Destee Nnamdi
With the original post by Childlike stating kneeling was fruitless and for show. Applied recently three years later had the entire worlds view of injustice to people of color.
To me any effort is worth effort. No guarantee the plan has been thought thru, shown it will be successful or in many cases is successful for 100% of the reason it was attempted. That effort in everyday life teaches us that.
So to measure any Man's and Woman's effort falls short because the fall / or result if any is isn't always immediate to any action or reaction. Keep On Keeping On!
As a people we are reactionary. That needs to be changed. We know all the reasons, and issues and have read if not experienced them.
The mere fact any one of any color is speaking out against injustice for another, or we are speaking out against it for ourselves is commendable and can't be discounted just my opinion /position. Arm chair warriors will weigh in. against white's speaking out against what their own perpetrate. Yet all know. That is the crack that aided the ending of slavery. Cracks all made ends all oppression.
Kneeling and flag waving speaks loud and forms a truth for those that were deaf and motionless before.
Nice article from todays NYT on protest art, i.e. flag waving.
