You really need me to explain the perceived grievances of some on the right?
You made the statement, explain!
Answer the question!!!
Well, first thing to understand is that there is nor singular, monolithic entity functioning as "the right." Its a coalition of different groups with different interests, just as is "the left;" a binary, two-party system is not set up to reflect interests in the manner of a parliamentary system.
For example, the white supremacist who targeted FOX News as well as the Washington Post. Terms like "right" and "left" aren't particularly useful in discussing factions such as these. That's why I took care to ask "You really need me to explain the perceived grievances of
some on the right" when you wrote "You still haven’t told me what the right is so upset about that they are killing."
Overgeneralizations are a major contributor to ignorance and ignorant statements-- "
they" are not all killing.
Moving beyond that, though, there are several grievances we could point to with regard to groups on the right:
1) Heritage-- The thought that the country is changing and the views and makeup of the country are drastically different from 50 years ago. You see this most heavily with the immigration debate now, though its really just a continuation of the
perceived oppression of "the Silent Majority."
2) Big government-- Related to the last point, states rights and a hatred of federal hierarchy has always been a refuge of those having their "personal liberty" attacked. Don't want government taking my money to support welfare queens, making me sit next to racial undesirables, etc.
3) Religious fundamentalism-- Religion speaks to core beliefs and encourages a "my way or the highway (to heaven)" approach. Thus the passion over gay rights, abortion, Christmas... these are all entangled, by the way, and the uproar about Christmas is about heritage as well-- "America is a Christian nation."
4) Distrust/disinterest in foreigners/foreign lands-- Again, this is intractable from the first point, immigration has been feared and hated because of the thought that it would change the core of what America is (which it inarguably has). You especially see this today in opposition to Barack
Hussein Obama (love the inflection on the middle name), fear of his background and opposition to his embrace of other cultures, his daring to say that America is not a Christian nation.
5) American exceptionalism-- This justifies the contempt some hold for the rest of the world-- we're better than them, anyway. I hesitated to make an individual point of this because its so strongly tied to heritage (there's a lot of interrelation between these basic points) but its such an important theme in American history and it also underscores our dealings with foreigners.
That's five for now, I might add some more later... I'd say this framework explains the most major grievances (though I could be missing something) and religious fundamentalism would actually be the least important of the above (though, again, it can't really be separated)...
Hope this lends some insight...
