'Politically correct' language that is used to avoid negative connotations like racist and sexist slurs is a positive. I out that in quotes because as far as I can remembr politically correct was a disparaging term for inclusive language and not using slurs.

As with everything humans do, it does get taken too far to the point of undermining clarity and that should be discouraged. If someone collects trash for their job, they are a garbage collector. Collector instead of man is a good change because women collect garbage ad well. But they aren't sanitation engineers if they aren't doing any engineering.

Using language that accurately describes something while avoiding stereotypes and negativity is good, but some of what gets pushed seems to reduce clarity and it really depends on the change. Wholesale support and opposition are both wrong.
