Hashtags and Scorn
Look, I agree that the hashtag #BringBackOurGirls will not, in fact, lead to said girls being brought back (see a discussion of this by Megan MacKenzie at The Duck of Minvera). But, I am not sure why it is necessary to be either a jerk about it, a grump about it, or a mocker over it.
At worst a hashtag like this is a small attempt to express an opinion and, at best, a means of bringing attention to a story (indeed, I expect a lot of people originally heard of the plight of the girls kidnapped by Boko Haram because of this hashtag story).
Clearly no one thinks this hashtag is going to result in the girls being released, so the scorn strikes me as unnecessary.
But, such is politics.
