The problem is that those candidates also support other things. If they donated money to these candidates, they are responsible for those other things too.
I like Hangouts overall, but the killer feature that's missing is a good gallery view where I can see more than 4-6 participants at a time. Zoom is really good at this.
Why would someone bring it up at every meeting? That's a pretty big straw man argument. I'm sure there are outliers that do that, but they are rare.
On the other hand, many gay folks are afraid to even mention their partner at all at work, even casually in the what that most people do. In that case, the belief that "gay rights are political" that some folks have are creating a toxic environment.
Companies themselves are inherently political though, just by existing. They exist in the context of society and are made possible by the legal structures created by politics. And they generally advocate for themselves within the political system (a good example is lobbying).
So there are certainly limits in the workplace and there is a line to toe for toleration and polite conversation, but saying "politics do not belong in the workplace" is pretty absurd.
