I've got no beef with taking elements from another's culture if it's done with respect and a decent understanding its meaning. The exceptions to that are religious and sacred symbols. It's not the taking that's the offensive part, it's the use of names, foods, and imagery, in a way that bastardizes the original idea that is the offensive part. If I follow a recipe for ghormeh sabzi as part of a dinner on world dishes, that's multicultural and my guests may gain at least a slight appreciation for a food from the Middle East. Maybe in the process they can listen to music from the region or learn about its holidays or history. If I dress up as a Muslim cleric and go around handing out jello shots, my guests have none the more understanding of Islam or the Middle East.
