Really, it's about expanding their thinking. Most Christians think they need to be overt with their faith, when that's not always the case. You could talk about what it can look like to live your faith in a secular world. At the end of the day, it's about doing whatever is in our hand with excellence, not about preaching to others. 99% of believers are not called to platform ministry. Yet every believer is a member of the royal priesthood (1 Peter 2:9).
Look at the examples in the Bible such as Joseph, Daniel, or Esther. They all were promoted to positions of prominence where they saved their people, not because they were great preachers, but because they solved problems no one else could solve and did their responsibilities with excellence. They demonstrated that proximity is power as they were put in positions to influence kings. When the time came they were in position to bring their godly wisdom to the situations to make things better for God's people.
At the end of the day, that's what is happening here. Q, along with patriot Anon's of all backgrounds are working together to take a stand for the forces of good. That's what sets followers of Jesus apart from every other religion out there. We respect and honor people enough to let them make their own decisions. Religions (even some Christian ones, unfortunately) try to make people conform to their rules. The fight we are in right now is desperate. It's an epic battle between good and evil. The stakes are eternal. We are modern Josephs, Daniels, and Esthers.
