You well up with frustration when others react contrary to your liking.  This is a very human response.  Do not berate yourself for feeling less than loving.  Simply recognize it and then shift to spirit-consciousness.  From this place of love, send compassion to those who do not think as you do.  What is compassion, but understanding mixed with love.  From this place of compassionate understanding you can now experience dispassion, which is not a lack of caring, but a lack of excitement.  Dispassion equates with peace, and is this not the optimum place from which to face all trials?
 
Radiate peace-filled love, and that will be your experience.
