His comment buys into and presumes a number of sexist tropes, primarily relating to the idea that women manipulate men using false erratic behavior and that there exist men, generally characterized in a way the author perceives as emasculating ("dramatic", "hipster"), who welcome this manipulation.
In all but the most egregious cases of sexism, it will be possible to find justifications for how the negative connotations could apply to all sexes. This is a pernicious way in which sexists recruit otherwise neutral parties to their defense -- our natural desire is to give the benefit of the doubt and particularly on HN, we love to find technicalities and loopholes. The key is that they will generally fall into existing sexist tropes, as this does, and more critically while they could apply to men, in the context provided they do not.
