Can problems (real or imagined) be solved by silence, with the lack of conversation?

If there is a perceived problem, cops overly shooting minorities to death, illegals, human trafficking for chattel or sex, honor killings, gunrunning, etc. if no one speaks of it because it breaches their ”ick factor”, twangs their kneejerk reaction, erupts one of their pet peeves, etc. how will the alleged problem ever move towards a solution or be exposed as not truly being a problem or issue in the first place?

Mod note: “gunrunning” as it is online, is not recognized by Fluther who suggest it to be spelled as “gun running”, in case it is a dictionary bug Fluther has.
