I don't see a double standard here. Rsther that there are conflicting rules and airbnb chooses the one to follow, that is in line with their choice which image to project if there is a choice to be made or if there is media attention.
They have a policy of inclusion and non discrimination on a prejudice.
They protect their hosts - that is- beside being I believe a honest conviction - also one of thrir majoring points to hosts.
Including people with strong prejudices themselves is one thing, if they preach, it's annoying for most hosts, and these will preach, they do preach publicly, but if they intend to go beyond still acceptable words, the choosen policy requires to protect other
members.
In the situation of the immigration ban blocking people already on their way , airbnb stood up to help and to say that they do not agree with such ways to proceed.
There was some discussion then, that they should not meddle in politics.that's choosing to be blind: big companies meddle in politics all over the world and probably since the first company was created. The current American president favours heavily polluting industries over the health of his people and the world's population 's wellbeing. Those decisions don't come out of the blue, they stemm from political and financial support and lobbying. The worst polluters dictating environment laws - that's companies / industries making policy. In the tech industry are a few big playersgoing against the current tendency, which I see as a small shimmer of hope.
The concept that you can't discriminate the discriminators is flawed. It's including people into a set of rules, who define themselves outside the set of rules.
