Denial of free expression is prima facie intolerance of human expression of opinions; when speech is suppressed, resentment brews, and when speech is outlawed, extremism is kindled and violence follows not far behind.

Whatever noble goal or intent of non-offensive public behavior you think you further by supressing freedom of expression (of others), you are not freed from this causal fact, or the fact that *you* are supporting what leads to worsening societal discord and ultimately violence.
