Answer and Explanation:
1. Freedom and expression is important because it is the guarantee that citizens will be able to position themselves and make their opinions public on several different subjects, and may even point out inconsistencies in any branch of society. Freedom of expression is a democratic requirement and as such is of great importance.
2. Freedom of expression can promote society's progress, by pointing out incorrect elements, disadvantageous managements, cases of leaders' default and ineffective policies. In addition, freedom of expression allows members of a society to point out how improvements should be made, who should participate in these improvements and how social, political and economic elements should be managed.
3. It is important to always respect any person's opinion, but disagree with that opinion when he defends misconceptions that hinder social progress. In summary, we must state that even when disagreeing with someone, mutual respect must be guaranteed.
