If your thread here isn't downvoted to hell...
...then you do not have an unpopular opinion. Whatsoever. Unpopular means exactly what it says. "Not popular". I've seen posts here get upvoted hundreds of times, and they say the most banal, generic shit imaginable. What having a significant amount of upvotes means, in a subreddit like this, is that more people agree with you than you actually think.
Does this make sense to you?
