Anecdotes are a very poor basis for drawing conclusions or establishing worldviews. They’re an even worse way to justify statist bans.
A pit bull biting a child does not mean that pit bulls should be banned. A Tesla automobile getting into an accident does not mean that Teslas should be banned. A person falling off a ski lift does not mean that ski lifts should be banned. An immigrant committing a crime does not mean that immigrants should be banned. A Muslim committing an act of terror does not mean that Muslims should be banned. The list of examples is as long as there are things and people which some authoritarians would like to ban.
Put another way, freedom is more important than fear. Every person and every experience should be judged on its own unique merits and should not be used as an excuse to issue sweeping bans which violate our rights and liberties.
