With content as dangerous as this, it is more about the lack of context in your post when viewed standalone. A screenshot of just your message without the surrounding thread would look extremely questionable. Much better if you actually titled the tier list.

It's definitely not you. This shit happened (and is still happening) on Reddit all the time, it's like there will always be a sizeable population that doesn't understand the concept of context and how replies to a thread are never standalone but always within the ongoing context of the thread. If they want to make a standalone comment, make a separate comment thread. But somehow that's too advanced of a concept for them to grasp.
