Friend Somkid,
All enlightened people in history are only very few compared to the population but still all of them like Buddha, Jesus strived for their whole life to share what they understood. They never gave up stating that these are fools who do not understand what I am saying. They are also ME as WE are all part of the same. One cannot discard my own mother, wife or family for any reason likewise for all our human broethrs. We cannot discard anyone for not understanding us. We have to make ways and means for them to understand. We lack the communication skills not they listening skills.
Any case, you are your own master. Take care. Always am here for you.
Love & rgds
