1. In this case, the fine line between personal revelation and general human rights could be considered

having been crossed. At least until considerably more equality awareness takes hold.
Similar adjacent post in this group, I put up argument with someone who disagrees with even display of the rainbow flag. It's taken quite some time to get some past the support for equality the flag represents rather than necessarily being a personal "advertisement".
There certainly are far more controversial symbols that tend to have a pro-oppressive connotation. "Blue lives matter" as opposed to those associated with BLM. That can be considered offensive, and by the behavior of many of those flying it... wow.
On the same token, should I object to a teacher wearing a Christian cross, since it can be considered symbolic of oppression? There's that fine line again-- all depending on context, usage possibly making it a matter of separation of church and state.
