People are weird about things that are irrelevant.
They have to be really upset about them, so that they become relevant and they have an excuse to be upset about them.

I just assume wishing death threats on artists/creators who annoy you is a fundamental way to talk about pop culture.

Just the other day, for instance, I overheard someone wishing that M. Night Shyamalan would get shot.

Extreme reactions [of the violent and abusive nature] are the classic signs of individuals displacing emotions and emotional turmoil onto third parties which they feel are causing them some sort of grief, as a means to alleviate said displaced emotion. To add that our societies are already horribly entitled and self indulgent, means that terms, actions, and other phrases are almost desensitized in their meaning. A classic case of "Kids get away with doing it, therefor it's done harsher next time around".
I also feel that there is a huge measure of jealousy. A personal observation; many who are incredibly jealous of the stardom or popularity of a specific pop culture figure/creation tend to revert to "hating on them". Sometimes they feel swindled, as their ideas seemed shunned [while they feel their ideas worthy of equal popularity], of simply another drop in the glass of "anti establishment" persona going to far. Either way, I think the irony and humor in this situation is that most people who hate something [with a burning passion] are also those who tend to love said content but seem "emotionally confused". As if their liking or the temptation of liking said content will somehow stand antithetical to their opinions/existence, and that somehow it will "destroy" whatever deep rooted emotional issue they have.
After all, Love and Hate are the EXACT same thing.. it's indifference that is the opposite to them.

That's kind of extreme.

The things that annoy me most are the following:
Monotheistic Religious Teachings
Racial Supremacy
Religious Supremacy
Military Supremacy
Government Supremacy
Giant Greedy Gluttonous Corporations
Patriotism
Anti-enviromentalism
