I guess it's about personal responsibility for self at all times.
That can be a hard concept in this day and age, but it's an important one.
What someone takes from a post is their responsibility, not anyone else's. That is how I see it.
Of course, forums have guidelines, and those are important too,particularly because of children.
But ultimately, we're each responsible for our own reactions, feelings and experiences, regardless of what others perspectives are.
That is actually quite freeing because it means each of us are allowed our own perspective. Or at least that's how I see it.
But you're right that no one can possibly know someone else's experience. It is up to the person who asked the question to take what reasonates and disregard the rest.
This too, is my perspective
