I've seen harassment campaigns (which ended in a lawsuit against the chief harasser) over association with someone who associates with a certain group. So even if you're a liberal you can get in trouble for associating with the wrong people or speaking at the wrong conference or promoting the wrong project.
Yeah, the argument that this will primarily target conservatives is probably incorrect; the baseline population of conservatives at Google is probably dwarfed by the population of mainstream progressives who would fail in some way, shape, or form to abide by proper woke etiquette and thus create an unsafe environment.
If you're remotely alarmed by what happened to James Damore, then you should be alarmed by a union that organizes itself around these sorts of values.
There's a certain kind of personality who needs to be a hero fighting against the enemy. It exists on both sides of the political spectrum. Both liberals and conservatives hate it when they see it on the opposite side but support it on their own side. When this sort of person lacks a clear enemy they will make one up. Some 10% of the group will always and must always be the enemy. Hope you don't end up unlucky enough to fall into that group.
The language of these organizers triggers too many warnings in my head around being that kind of personality. No matter which side of the political spectrum they are on I try to not support these personalities.
