Why is Earth of such interest to the Orion Empire?

[Ohr Ein Sof]

We here being STO it’s best to send love and move along eyes of love intact.
My 2 cents.

An active sending of love may be a STS act, out of the pleasure that one feels in doing so.
One sends love because it makes one feel good, not so much due to the service one provides by doing so.

The act of actively sending love (without a previous request from other-selves) may not be a STO act, for it is based and centered on the Self, first and foremost. Unsolicited actions are no different than what the so-called Orion Empire does, enslaving other-selves. Enslavement isn't necessarily violent, for it may be vested in a costume of love, though an imposing, unsolicited love.

Such attitude isn't just being as much as it is actively doing something out of a desire to experience certain things instead of just being, selflessly and unpreoccupied with anything.

You may have a decent point but Love cannot enslave. Love does not have the ability to enslave or ensnare. Perhaps we should think of it this way, it would be the same to feel and think; "I love that other self" and by doing so, you are in fact sending love. You cannot go wrong when you love another. Just by thinking you love someone, you send it; as it is an intention that is being sent from your heart, by the heart, out of desire to love another.
