We live in a world where common words are generally used in ways that are in direct contradiction of their meaning

This is exactly what you are doing. A few minutes with google will convince any impartial reader that the word censorship is correctly applied in many contexts, including self-censorship, which do not relate to the use of force of violence.

For example http://www.merriam-webster.com/dictionary/censorship:

"a. the institution, system, or practice of censoring"
"b. the actions or practices of censors"

"censor: a person who examines books, movies, letters, etc., and removes things that are considered to be offensive, immoral, harmful to society, etc."

Government or otherwise violence-enforced censorship is a form of censorship only, it does not define the term. Please stop attempting to redefine it.

Removing content (believed to be offensive, immoral, harmful, etc.) from view is censoring it. This may be a good or bad, depending on the context and the value system of the person making such a determination.
