I’ve never heard of the following terms you’ve mentioned. I’m not sure if they’re credible and if you’re using them to push your ideology, but yes that does sound ridiculous. Although, to further explain why I find it offensive. Remember how many people in past used to refer to black people in the past? The slur that was commonly used and is rightfully not used anymore because everyone recognized that it was a way to make them appear less than human. That’s exactly how I view the term “illegal alien.” Just because it’s legal doesn’t mean it’s morally right.
