When people go to a sub about opinions and don’t say their opinion in the title

Like recently in this sub, I’ve seen several posts titled “Here are some of my pet peeves”, “My pet peeves”, etc.

I’ve seen people in r/ControversialOpinions say in the title… “I have a controversial opinion”, etc.

I haven’t been very active in r/UnpopularOpinions, but I am a member and have posted there. Still, I don’t doubt that these types of shallow posts show up there as well.

You don’t need to announce that you have an opinion in a subreddit about opinions. People will automatically know where they are, even if the post just randomly showed up on their feed and they aren’t a member of the sub. Just say your opinion in the title. That’s how the subreddit is designed.
