The real reason for calls to use soft language is to blunt the effect of powerful inspiring words so that their effectiveness is lost.
People claim to be easily offended by the language and common everyday words. They use it as an excuse to avoid working on real issues. Imaginary problems are much easier to deal with than real problems.
This is an urban liberal problem found only in big cities. Understanding this is important to avoid being distracted by them.
Use of Politically Correct and contemporary soft language makes us weak. Instead of focusing on real issues and tackling them, Political Correctness and soft language focuses on tackling imaginary problems which seem to grow in size no matter what. The real issues are never addressed, and people are demoralized.
