if we see a split between progressive tense and other tenses, we have to find out the reason to use progressive.
if the verb is action verb, progressive means that the action is happening at a point of time or in a period of time
when you come, I am eating my meal
if the verb is stative , such as to be, progressive means that the status is short.
"he is being good " means that "he is being good not permanently". it is possible that he normally a bad boy
so, if we use "kangaroos are being distinguished from" , we means the difference last a short time. this is not logical
