When Zimbabwe keeps their own citizens from killing lions, you may have a point - until then you are simply repeating a globalist’s pantload.
The question is it is legal for people who are NOT citizens of Zimbabwe to kill lions? If it is illegal to do so, we should abide by their laws.
Put lions aside. It doesn’t matter what the law is. If they say something is illegal in their country, whether for everyone or just non-citizens, then that is their law. When visiting another country you abide by their laws, whether their own people do or not.
Do you want people coming here and breaking our laws?
