It is easy and requires much less forethought and intelligence to take slag someone, especially with so many of these notions taken well out of context, or enhanced with various forms of propaganda found equally in right and left media sources. Not that it isn’t important to point out atrocious behavior, but often these tirades end-up being more subjective than absolute.
This tends to go well beyond politics and it seems this practice of always searching for the bad in a person, may subtly change your own heart in ways so that eventually it will be primarily all you see in anyone – good or bad.
Being conservative, doesn’t make you a monster and neither does being liberal. There are good and honest folks on both sides and everywhere in-between.
