Today is a day to seek first to understand someone before judging them.
You might find your reaction to be a little different. Who knows you might even develop some empathy towards then find out you more in common than you thought.
Remind yourself than we are all doing the best we can with the limited knowledge and resources they we have. Treat other with the same compassion you would want to be treated with when you are some distance from source.
If none of those things are possible send them love and light and move on.
