A series of steps you may follow if you wish to be more mindful about cultural appropriation:

Try to identify parts of your outfit or vocabulary that may be borrowed from other cultures and envision how a person of that culture may react to the way you are wearing or saying it.
Think about whether the piece of clothing or phrase in question is being used respectfully and is aligning with the traditions of its cultural origins.
Can what you are wearing or saying have the potential to perpetuate stereotypes that exist about a certain culture?
By following these steps, we are better fit to identify cultural appropriation and are being sensitive to and respectful of all cultures.

So just a reminder: all cultures should be separate, respect is shown by isolation and prohibiting wear of cultural symbols, and it's okay to project your feeling of insecurity onto minorities because you assume they probably feel sad about things like that.

Also, please cease wearing the following clothes immediately because they were influenced by other cultures:

Boots, ties, peacoats, bomber jackets, t-shirts, tuxedos, and 8-point caps. Those are all from foreign militaries and they deserve to be kept culturally pure. Other items from various cultures include Uggs, denim jeans, cowboy hats, ponchos, Hawaiian shirts, berets, moccasins, and eye liner. For a more complete respect of cultures, please just stop wearing clothing, listening to music, watching television, enjoying art, or partaking of drugs. Because it's your job as a white American to think carefully about what you think is offensive to others.

Hehe, you made me laugh. Well done.
