Oh dear! Should I really answer that or should I ignore it, as you did my questions of you?
If you are “truly curious” then I must wonder what has been the extent of your reading. It is difficult to believe that anyone interested in writing would not be widely read and also acquainted with the main motivations for writing, one of which, of course, includes the desire to focus attention on an issue and encourage or promote a particular reaction to it, i.e. a change on the reader’s part.
It strikes me that your question is perhaps somewhat disingenuous. There was a time when I would have responded in kind but I have long since recognised the pointlessness of that and have no wish to contribute towards the acrimony that usually accompanies it.
Instead and despite your avoidance of my own question, I will simply suggest that you read more widely and, perhaps, more perceptively. Your question ought to be readily answered if you delve into works of any of the following significant and, in my view, great writers who wrote to create change. This list, of course, represents only a tiny proportion of those who have done so.
