Damore worked at Google, i.e. in the Bay Area. The Bay Area has a certain political bent (left), and running counter to it has real consequences.

But other places in the country have a different political bent (right). Chick-fil-A's anti-LGBT stance actually increased its sales (for a time, anyway). [1]

You can see this effect play out similarly when Trump says something that rankles the Twitters of Silicon Valley and New York, but which gets him even bigger approval ratings in the red states. All this to say - your points might feel like activism in the Bay Area, but that doesn't make the above poster's claim that it's mainstream conservative discourse false.
