Why do people hate queen's pawn opening?

I have noticed that a lot of people seem to dislike the queen's pawn opening. Does anyone know why? 

ITS STUPID

'1 d4 dull & drawish' - Fischer
'I have never opened with the queen's pawn, on principle' - Fischer

Ok but what about it makes it so boring?

When I was 800-1300, I did not enjoy the grind against a London System and book theory/opponents preparation in other lines.

Then a coach taught me there are 5 different ways to beat the London System and one defense that was flexible which suited my dynamic taste against d4 and c4.

Now I enjoy d4 games more than the Sicilian.

Everyone has different preferences.

These days, I tend to dislike the King's pawn opening. Why? Because of 1.e4 e5. I find the games too drawish and dry.

But that's just me. Other players love e4 e5 games. It's all a matter of taste ...

It's more boring because it's positional. But to me, that makes it less boring because in the end, positional approaches lead to amazing tactics. Ok, fair enough, only sometimes. Still, I'm a d4 player pur sang and the only e4 opening I like is the King's gambit. And I think grinding is interesting and adventurous, much like climbing the everest instead of taking a helicopter.

Also, QPO's in general are gaining in popularity, not just the queen's gambit.

Hear hear. Also, with e4 e5 you can't really challenge the center with 2. d4 or 2. f4...whereas in the QPO d4 d5 the center can be challenged with c4 - creating dynamism right from the start, before adding pieces.

As white, I never play 1.d4.

As black, I hated playing against 1.d4 for a long time because I was always losing. Since I started playing 1. …,Nf6  instead of 1. …d5, however, I have also started to win ( I don’t know why : some psychological effect ? It's a mistery. ). Now I love playing against 1.d4  !

As white I keep avoiding it, seems to me too complex to manage.

Most chess players are beginners. Most beginners improve the best by studying tactics, and enjoy tactical attacks over slower positional maneuvering. As you get to higher levels they probably even out as it becomes less of what you are good at but rather what you enjoy doing more.

I think it’s quite understandable that most people would prefer flashy and impressive tactics.

because they be spending all their time practicing kings pawn openings and when someone plays 1.d4 they get caught completely off guard

Because they play 1... d5. I didn't (still don't) like QGA, QGD, Slav, Semi-Slav, and Tarrasch defenses, but ever since I began playing 1... Nf6 or 1... g6, I've begun to really enjoy playing against 1. d4, as now there's no chance of a QG game, but I still get to enjoy complex theory and crushing London/Colle system players. The fun thing is, if you learn the Alekhine's, Modern, and Pirc defenses, you can start playing d4 c4 Nc3 (especially KID, Benoni, Gruenfeld, and Neo-Gruenfeld) positions even against 1. e4!

Queen's pawn games are more closed and positonal with more peices on the board - now, that doesnt mean it's boring, that just means that there will be some time before every peice goes into an attack while in e4 games peices get traded faster

I love the queen pawn opening. But that was like 2-3 years ago I started off with d4.
