Definitions for "gyp", "gypsy":
- a negative act or characteristic (being stolen from, cheated, over charged, etc.)
- a perjorative for a specific group of (minoritized) people in Europe
Originally, it was commonly assumed that "gypsies" came from Egypt. More recent research suggest they came from northern India over 1500 years ago. So, a misnomer -- not unlike referring to indigenous Native Americans as "Indians".
Some thoughts / advice on Racism / the act of "othering" or minoritizing groups of people:
The concern about being "PC" is dismissive, and usually missing the point. If you find yourself saying "I don't know if this is PC to say, but..." the right answer in that moment is to listen to your internal warning there, and just stop talking -- at least until you can learn more / clear-up whatever it is you're unsure about.
"PC" is often used to by folks who feel the need to justify (or otherwise, don't want to 'get in trouble for') their own ignorance or insensitivity by blaming the target of their language for having an 'other' status, or being too sensitive. The reality is that if you're going to be offensive, people will see and feel that, regardless of how you prefix it. Saying "PC" first won't make you sound less ignorant or offensive.
Rationalizations about not intending to offend someone are not all that helpful, because the offended person is reacting to what you 'actually did', not what you 'intended to do'. A car 'actually' runs over your foot, you get hurt, regardless of what the driver intended. If someone is calling attention to what they intended to do for the sake of repairing damage, then it can be more helpful instead to acknowledge what they actually did.
If you really want to understand and engage with this stuff, you can. It's a lot to learn...but it's not difficult. The barrier for a lot of folks is the worry about looking like a bad person, or looking like they don't have all the answers. Truth be told, nobody is going to penalize you if you do nothing, especially if you're part of the dominant culture or group. But if you try to learn more, people will generally see and respect that. It's OK to mess this up -- part of the learning process.
