We get it. Halloween is the one day a year that grown ups get to play dress-up and assume an entirely new identity. But that doesn't mean that everything is costume material.
Reducing an entire cultural, ethnic or religious group to a costume strips those who belong to those groups of their identity and history. What you may perceive as being creative can actually be deeply offensive.
In the spirit of having fun and being respectful this Halloween, steer clear of these culturally inappropriate costumes.
