Is that your way of acknowledging you don't know anything about this?
Because trust me, this is not simple at all, and since you think it is, it just means you don't know anything about it.
This is understandable, a lot of people don't. But you should avoid posting about it, there are some VERY motivated people who post about this in every thread, and downvote, and flag. Don't be one of them, they are motivated by hate, and that's not a good place to be.
Why should I trust you? Nothing you've written here has inspired confidence in your ability to accurately report information or even understand why the people you interact with act the way they do.
