Department of Public Works employee Eric Batman claims that having to see a Progress Pride flag flying outside the department’s Alhambra, California, headquarters during the month of June effectively forces him to “celebrate, recognize, and solemnize conduct and actions that he views as sin” in conflict with his sincerely held Christian religious beliefs, according to a lawsuit filed in March by anti-LGBTQ+ evangelical nonprofit the Liberty Counsel.



How is a pride flag an opinion is a pretty fair question to this statement. You compare it to an opinion, so it must be comparable right?
All flags are an expression of opinion. Even the pride flag has different versions that include or exclude different sub-cultures and allies.
