But...but..but..under your avatar says Poland..

Polish music makes me wish it wasn't.

Okay,don't put any up:-)

Here are some more:
People who think that one's birth or legal name is somehow more "real" than the name the person actually uses.
People who refer to transgender people via their birth name and pronouns. (For example, using the pronoun "he" when talking about Caitlyn Jenner.)
In most cases, anyone who uses the term "SJW". (Note that I did not use that term here; I only mentioned it.)
People who assume everyone else follows or should follow their religion.
People who don't see nonreligious people as possibly being good people.
Computer games which make assumptions about the player or created characters.

Two examples from that last one:
In Wizardry 5, there is one character who asks the party "You boys wanna go for a swim?" Excuse me, but my party is a party of girls! (The Wizardry I manual explicitly states that Wizardry is a genderless game (but English isn't) in reference to the use of male pronouns in the manual.)
In Wizardry 8, there is one point where you need to have one of your male characters consort with a certain demon. In the unpatched game, if you have an all female party, you can't continue past this point. (Especially embarrassing since the game's designer and producer were both women.) (In case you are wondering, the 1.2.4 version lets a female character consort if you have no male characters.)

Edit: Corrected spelling of Ms. Jenner's name

What do have against, say Penderecki, Kaczmarski or Lorenc? I can name many great polish musicians here. Sure not everybody likes their music, we are after all different but there is not a single reason to be ashamed of their creation. And sure again there are many tacky polish bands but I don't think they are in majority to justify such a generalization.

Mornings. Nothing good about them. I suppose inherently there's nothing wrong but they usually accompanies both with too much sunlight and too little sleep, two things I can't stand.

Standing in line/queue. What a waste of time..

And then to be told ''Sorry Sir,but you need to go to window 6 and guess what (yep,another line).

1.) People who drive recklessly on the road. If they want to endanger their own worthless p.o.s. lives, then that is their business. But they have no right to be a lethal danger to other motorists on the road, pedestrians next to the road and possibly even passengers in their own vehicle.

2.) Pompous teenagers and young adults, particularly male ones. Often it also overlaps with 1.) I encountered one earlier today that came up behind me at a ridiculous speed in a residential area. After spending a couple of seconds at an unsafe distance behind me he blared past, also incredibly close, and over a solid line. I kept to the speed limit and caught up with him when he had to stop at a red light. As I approached the intersection the light turned green so I leisurely drove past him (there were two lanes and one was open), and took a quick look at the driver. He fit neatly into the above category and gave me the biggest 'I'm-the-shit-don't-you-know-it' look you've ever seen.
I also knew this young beautiful girl in my school, that sustained light brain damage and has been walking with a limp ever since she was in an accident. How? She was a passenger in car and the young dude that was driving was also driving like a maniac down a kind of back road. There was a tree or branch or something in the road, and he was going way too fast to stop in time of safely swerve out of the way. He rolled the car, and left this young girl with brain damage for the rest of her life. Guess it was worth it to show off to his friends in the car.

Seriously, I have no time for idiots like that. They can go swimming with bacon flavored swimming trunks in the Indian ocean for all I care.
(sorry, bit of a rant that)

I'm speaking of popular music. The lyrics... You know that our countrymen are tasteless.

Do you think it's worse than in other countries? I certainly don't. There are a lot of tasteless music all around the world. But yeah the more you can understand the more pain you feel ;)

Since the topic of music has been brought up, I'll mention what I hate in terms of music:
Electric guitar: It literally gives me headaches.
Excessive constant percussion
The singing style common in rock music and all related types (basically any sort of American popular music)

I could note that I don't hate all music: I love classical music and am an amateur musician myself.

I hate myself. Does that count?:P

Well,it's personal and it's hate so yes that rates:-)

Hypocrites, rationalized assholery (especially through populist legitimation discourses : "greed is good", etc), charity (supporting policies that crush people, but occasionally patting the victims on the head to feel super humanist), political manipulation ("according to my graph in 50 years 380% of the population will be muslim, by the way terrorists are also muslims"), anti-intellectual backwardness ("my grandfather's grandfather knew better than those so called scientists who are all homosexual communists anyway"), and double standards ("hey, it doesn't qualify as such when our clan does it"). And personality cults. And fetichized symbols mattering more than real flesh-and-blood people.

Also mosquitoes.

Right now? Not getting enough sleep.
