This is from a newspaper article: "we would like to hear from people who have been protesting against the controversial ruling." "If you have taken part in protests we would like to hear from you".
So first the present perfect continuous is used and then the present perfect simple. Any idea why? Could they just as well have said: "Have you been taking part in protests"?
My question is: is the continuous used because people continue to protest or could it be they have taken part in one protest and the continuous is used to emphasize the duration of the recent activity?
