Cause it doesn't work that way. Love is a very wonderful vibration, one that should be generously used to those who deserve it and who have earned it. Light only cheapens the vibration by blanketly trying to 'convert' Dark. It won't work. If 'all there is love', you have imbalance.
Love is countered by hate.
2 sides of the same coin. Bring the love and hate into the refinery to melt and make the wonderful Balance emotion which has no English word to describe. So, anyone who pushes the love the Dark is actually assisting the reptilians and their Dark allies in keeping the planet down. Dark respects strength and lack of fear. Think about it.
