"The detoxification of masculinity, progressives say, is a messy and necessary process; sore losers of undeserved privilege don’t merit much sympathy."
That was the author, briefly stating, what some progressives think. The author neither endorses or condemns said viewpoint. Before this sentence the author writes briefly what some conservatives think. Right after the sentence the author quotes an expert on the topic whose scholarly work tries to avoid moralizing about the causes of the problem and discuss what is going on. This is all obvious if you actually read the article and can understand that a reporter can write about the views of some people without endorsing those views.
