There is whole genre of media that is mostly concerned with "here is how you should feel about X". http://Vox.com is a good example, but it exists all over the place. The fact that this genre (voluntary auto-indoctrination) has a market alienates me from humanity.
Personally, I don't think that "we should". I am not even entirely sure that I should. This reaction in me is a thing I observe. The question why I have that reaction (I did not choose it) and many others don't is interesting to me. It is probably not primarily a moral question.
