Take a step back and a nice deep breath and consider why you might have been downvoted. It may have more to do with the tone of your delivery than the actual content of your message.
Lashing out at those who disagree with you with baseless accusations is counterproductive.
People are very happy to exercise their ability to punish others when given that power. It's gotten out of hand here.
Edit: here being HN, not necessarily this thread.
What you're saying doesn't match what I typically observe on HN, which is (a) that most downvoted comments have something wrong with them, not just an unpopular opinion, and (b) inappropriate downvotes usually get canceled out be users who see a good comment faded faded and give it a corrective upvote.
