The focus on language without any critical examination of why language matters is a hurdle. Its a solution that is reached by people just starting out with anti-racism. Our first instinct as allies is to say "what do I do?" and watching our language is one thing we can do. The problem is that we tend (general "we") to find something to do that makes us comfortable, and a disturbing amount of people are comfortable just trying not to offend anyone without digging deeper into why.
