My question has been downvoted twice after 10 views. None of the downvoters left a comment. Is that normal on PSE?
Edit. Now the question have been closed (by unknown people) as "off topic". One downvoter, Ted Wrigley, left two comments. In one of them he claimed that the question is a duplicate, difficult to understand, polemical and argumentative without giving any evidence. I asked for clarification, and got another comment consisting of pure insults. Again, is this normal on PSE?
Edit 2 Since my question has been deleted together with all comments here is a copy:
Simple arithmetic question
Let the number of people in the USA be x. Let B be the population of African-American people in the USA. Denote the number of people in B by b. Let k be the number of people in the USA who commit violent crime. Let m be the number of people from B who commit violent crime. Finally let a be the number of people in the USA killed by the police and c be the number of people from B who are killed by the police.
What is bigger, c/b or m/k? The answer which I am looking for is simple "less than", "greater than" or "impossible to tell" and of course I am looking for a justification of the answer.
And here is a comment I received, flagged and mentioned above:
