I totally agree with you-it's not 'post' in that it will always be a current issue. But in the piece I meant it in the sense that the power of the movement, its momentum has somehow fizzled out. Where there were whole magazine issues dedicated on racial politics, newspapers once more 'dropped' the topic as the news cycle shifted.When people such as myself insist on the importance of the issue, one hears things like 'it had its moment'. Thank you for highlighting in your comment how current #BLM is!
