They asked the political conversions be kept out of work channels, but continued to encourage people to be active politically, active on social media and even active at work using other platforms.
Framing the entire thing as some extremist plot to silence dissent is absurd.
If someone wanted to come into work channels and constantly tell people about their religion, why they should convert and why other religions were wrong would you think it’s okay to for the business to ask to keep those conversations outside of the main work channels?
