"We should be eternally vigilant against attempts to check the expression of opinions that we loathe"

This quote by Oliver Wendell Holmes, Jr. is a suggestion to be continuously familiar with attempts to limit the expression of opinions that we disagree with. It is necessary to bear in mind that even if we disagree with someone's opinion, we ought to still enable them to express it. We ought to not try to silence those with whom we disagree, as this is an infraction of their right to free speech. We should instead strive to participate in civil discourse and dispute, and to utilize our own words to express our own opinions. This quote is a tip that we must be watchful in securing the right to complimentary speech, even if we disagree with the opinion being revealed. We must not permit our own predispositions to avoid us from allowing others to reveal their viewpoints. We ought to instead make every effort to develop an environment where all viewpoints can be heard and appreciated.
