On the negative polarity here on earth.

[Meerie]

I don't think that is possible to infringe on someone else's free will by sending them love... I recall having read somewhere that if you send someone love and the entity does not accept it, the energy goes elsewhere where it is needed or "return to sender", which would not be too bad either

In the case of negative entities- especially highly evolved ones- the "return to sender" function might come along with an additional surprise.

and what would that surprise be? what could harm you if you are in a state of love? you sound fearful my friend
I don't believe in those so-called negative greetings. If there is negativity I am usually able to trace it within myself, instead of blaming it on some outside "evil" source.

This 'love' was not requested, nor was it welcomed, and look what came from it? Strife on all sides.

Precisely. And yet, this connection is missed. If we are looking for evidence of the unforeseen consequences, we need look no further than to our own discussions right here.

Again, I invite everyone to look within, instead of blaming the "controversial" subject of whether or not to send love to those of Lucifer for the forum strife.
It was not the action of sending love but rather your REaction to it that caused discussion, was it not?
