This is a question a friend of mine asked. If you ask me that, I say that they're both equally bad. Both are obnoxious sheep, that don't have almost anything legit to say about the series. However, currently right now, the Halo haters are more vocal than the Halo fanatics. Yet, they don't get as nearly as a bad reputation as the overzealous fans. They act just as immaturely as the fanatics with comments like: "Lolgaylo!", "gaylo is teh worst game evar!!!", or "ony faggots playz teh gayloz!!". Trust me, when Halo Reach is released, the internet will be swarmed with them and it will become a battle ground between the fanatics and the haters. 
 
So yeah, they're just as bad as the fanboys, but they're more vocal on the internet. One thing is for sure though, Valve fanboys are worst than both. :P 
 
(Before anyone says anything, let me say that I like Valve and their games.... A LOT) 
 
EDIT: 
I take almost everything I've said back, after watch this video: 
 
  

is it just me, or are halo fanboys very uncommon now? 

Great!  Now you will be hated by Halo haters, fanboys, and Valve fanboys alike!

I'd say that the haters of most things tend to be worse than the fanboys.

I agree with the Valve claims. But, it's almost natural that whenever a major game in a series comes out, all the haters team up and unleash hell onto the fanboys. Personally, I think fanboys are more annoying than haters though.

Both types are bad.
 
We need some more real gamers who care about how much  fun the game is and what it could mean for the industry as a whole.
I kinda like what Reach is gonna offer, it's so much more options and modes then most shooters offer nowadays, and that without DLC!

I don't understand how someone can hate the franchise. They're well-made games. I don't particularly care for the style, but I respect the product in terms of it's build quality.

" I'd say that the haters of most things tend to be worse than the fanboys. "

They are both vocal, they are both stupid and no one gives a fuck who is worse.

It's kind of a more complex issue than some would make it.  I just don't see Halo fanboys causing trouble anywhere like I see Halo haters, in fact I never see anyone say "Halo rocks, everything else sucks" or "You're dumb if you don't think Halo is the best game ever".  I do see a lot of people say "Halo is only good if it was your first FPS", or "You're dumb if you like Halo"

Indeed. "

Would you say that "fan" is different to "fanboy"? I'm a halo fan in that I'm interested in the games and the fiction behind them, but I don't care enough about it to defend it against halo haters, does that make me a fanboy? I basically don't care about whether or not other people like or dislike it, everybody has opinions, that's what makes us individuals.

I would say haters, as Diamond said i more often see people making those comments.

Halo's gonna hate...or something.

What is up with all of these Halo fanboy/hater threads lately? Halo is a quality franchise. Anybody who bashes it is an idiot... but people who only limit themselves to it and miss out on other great games are also, indeed, idiots.

Haters of anything tend to blow small issues (sometimes even non-existent issues) out of proportion, while fanboys blindly ignore flaws and make ridiculous claims. I'd say fanboys of anything are worse.

Well, haters are annoying.
Fanboys are fine, they're just enjoying their thing and stuff, not looking down on anyone for their opinion.

Is this the new fad now? We're supposed to hate on the Halo haters? Alright, give me a minute to work up something. ..........................................................................................FUCK YOU Halo haters. You guys suck hairy ass.

Thanks for clearing that up, bud. "

I agree.

No, even after watching that horrendous video I still say Halo fanboys are as unbearable as Halo haters.

Halo is the franchise that I can always rely on for awesome FPS action. It's overrated as fuck but I don't give a shit. 
 
Besides, there aren't THAT many Halo fanboys anymore. They've all moved onto the cesspool known as Bungie.net. Apart from a few comments here and there, there are much more Halo haters plaguing the internet than Halo fanboys. 
 
A friend of mine said it best; "the only people that's dumber than Halo fans are the massive anti-Halo fans... and Naruto fans... and My Chemical Romance fans."
