Should one apologize just for being angry?

I don't get it.
why do people think others shouldn't be angry?
what the hell is wrong with that sentence?!
well, for one
Anger, is primal, primitive, and like many things
we claim to have outgrown, it is very much a part
of our genetic makeup, our blueprint
much like hormones, hunger and superficial horny'ness

if you think people can decide to be angry or not
or you go on youtube just to watch freak outs and tisk
or think that this is a typical angry man
"won't serve me chicken nuggits?!
screw this, I'm flippin out right here, right now"
you'd be wrong
because that's not anger
that's dear old stupidity overwhelming the mind
of a once reasonable human being
in much the same way as it does, when people say
Stop being angry,
you know what, stop falling in love
Stop disliking your ex
Stop being Happy.

Anger is a Freaking emotion
Its not everyday you stop and think
"hey, Imma go fall head over tits for that one"
No! same way people don't think
"Imma go on a drunken rampage through the street
which people will never let me live down,
and you know what, this time, I gonna do it over
the peanuts"
So unless your truly moronic enough to believe
that's what happens
stop trying to make a problem go away by pointing
fingers at people who flip out
because most of the time, their as much ashamed
of their actions as you are of witnessing them
