I've personally flagged far more articles on this topic than I usually do. However I am not "on the left". I consider my politics to be slightly right of centre. I have expressed no public view on the content of the Damore memo. But there's been so much sound and fury that only the strongest signal is now welcome in my feed. I did not flag this YC posting; it is, by contrast, very low noise. I thought you can repudiate a flagging, isn't that the "vouch" control? I'm not familiar with exactly when it is or isn't offered.
