Absolutely. I usually see this type of posts on twitter where people are simply mad that they can't shit on imigrants like that in there.

Language as a whole is subjective.

This feels rather hand wavy and reductive. The bar isn’t “Wikipedia is completely unbiased and objective” - that’s a fool’s errand, it can’t be done. But we still strive to account for biases and reach for objectivity as best we can, and there are situations where language (with its subjectivity taken into due consideration) and claims clearly are not an attempt at that.

Correct. All language is subjective, but not all language is equally subjective.
