I disagree. It's an overused defence: voicing idiotic opinions is "having a unique point of view"; being rude and domineering is "having an outspoken and blunt demeanour". Your opinions should stand on facts, not your I-don't-give-a-shit attitude. The difference should come from your interpretation of them. Respecting so-called controversial figures leads only to a downward spiral where we encourage bad behaviour.
Hacker news, in my experience, respects different opinions if they carry any weight. A thread on Uber has both who attack and defend Travis Kalanick. Controversial opinions, unfortunately, often means saying groundless shit and later, defending them with "I-am-a-contrarian" attitude.
