Navy's 'extremism' training says it's OK to advocate for BLM at work but not 'politically partisan' issues

The US Navy’s "extremism" training says it’s okay to advocate for Black Lives Matter (BLM) while at work but sailors are not allowed to discuss "politically partisan" issues, according to training slides obtained by Fox News. 

The answer given by the Navy called BLM a "public policy issue" and gave the green light for advocating for the organization "as long as the behavior is otherwise lawful and the advocacy is not politically partisan in nature." "Advocating for or against a public policy issue (as here) is authorized as long as the behavior is otherwise lawful and the advocacy is not politically partisan in nature (e.g. it doesn't specifically address a political party)," the slide reads. "If the discussions make you uncomfortable, discuss the matter with your boss or another supervisor."
