And if they aren't, they hardly notice and don't react in either a positive or negative way. True self-love does not engage the ego at all. What you consider a strong ego is, for the most part, a highly compensated personality. A weak ego is recognized as low self-esteem. Self-love is peace.
Peace is the absence of conflict and a point of balance.
The balance point is a magnet for the aspects of reality that are aligned with the stencil of peace and love. Through self-love all other love is available for you to give and receive. Self-love is very alien to the Earth world, so that in a sense, it is bestowed from a higher level. Many guides and angels are available to assist you to accept the gift of Source of all Love. The Earth's future, as a world species, depends on peace on Earth, and this depends on a critical mass of self-love to attain peace.
