This is a point of concern I have that I rarely see others bring up. The problem with A is that it creates a loop hole as all the next government official has to do is pick a host that aligns with their own views to communicate to the masses.

Imagine a future president picks a Catholic forum to make the same sort of announcements that Trump currently does, specifically a catholic forum that bans any advocacy of pro-choice discussion. It is relatively easy to find a similar forum on any side of a modern hot button political issue.
