<i>If HN has &#x27;groupthink&#x27; opinion that is completely wrong on a political or other controversial issue, I would politely abstain.</i><p>No way! I love commenting on political and controversial issues. Never let a fear of downvotes act as a chilling effect on your speech. If you believe you have something truly valuable to add then get it out there!<p>I often find myself surprised that I&#x27;m upvoted for swimming against the current. It may turn out that there were multiple people who had the same idea as me but they were staying out of it until I commented.
