Why do you guys hate him so much?

It's a distillation, but true. 40k's aesthetics and factions are more refined and more interesting.

Were you around for the Storm of Chaos campaigns and how pissed off people were when GW fiated the whole thing?

That's maximum soyboy level. Indeed, it's your dudes, there aren't racial quotas for miniat yet.

>He's a fucking idiot. The point of 40k is that EVERY option is horrible,
In your opinion.

>turning the actually slightly more horrible faction into noble renegades because you're butthurt about Nazis misses the point completely.
I don't think he presents chaos as the good option. Everyone who messes with chaos ends up some degree of fucked. He does however present the renegade marines as being more complex than just 'the bad guys'. This doesn't make them sympathetic IMO, just more rounded. His protagonists are still terrible people who do horrible stuff, but you understand their reasons for doing it, even if these reasons wouldn't resonate with us, the readers.

I don't understand what you are talking about in regards to nazis?

I don't mind that too much, other than edgelords people rarely think of them selves as the "bad guy"

I remember an old White Dwarf when Andy Chambers talking about the 2nd ed chaos Codex when it came out that he wanted to portray the faction as angry, bitter and feeling betrayed rather than inherently evil

whiny chaos is and always has been worst chaos

>Were you around for the Storm of Chaos campaigns and how pissed off people were when GW fiated the whole thing?

Again, bad execution and Storm of Chaos wasn't meant to end the setting. It was meant to create a new status quo. GW said so themselves. Why are you like this?

The general arc of BL's HH series has been extremely generous to the fallen legions whilst shitting constantly on the Emperor for basically everything he did at any point.
It's not that the traitors are rounded, it is they are being fed "It wasn't MY fault" excuses.

I enjoy his books, but I have no opinion on him personally.

eh not whiney so much as relatable, he wanted them to have a reason to fall to the predations of Chaos beyond being just bad dudes.

>Why are you like this?
Why are you lying so wilfully? The global campaigns clearly showed people don't give a fuck about Chaos OR about the "Chaos is the big bad" narrative. It's literally the disconnected writers clique at GW who want to push that narrative.

>In your opinion.
Have you read anything related to 40k? At all? Even the video games?

>Everyone who messes with chaos ends up some degree of fucked
Absolutely, but ADB has a clear trend to represent the setting's villains as clear dindu nuffins by intentionally leaving out their more horrific characteristics, adding sympathy character's like the Word Bearer's confessor woman as cheap emotional catalysts and generally present them as making terrible decisions and being fucked over by chaos as a direct consequence of the Imperium/The Emperor/Loyalists/Authority being evil.

The Word Bearer's and Night Lords' books are a great example of this.
Just compare Betrayer or First Heretic to Dark Apostle. Even though the latter actually has slightly worse prose (which is probably ADB's on area of any competence), the characters, plot and overall feel of Reynold's is so far superior it's not even funny.

Again, Reynold's rendition off the Word Bearer's is both more evil and far superior than ADB's. The tragic misunderstood victims who are good at heart and got thrown under the tracks by the evil evil authoritah so they had to turn to other masters is a narrative that fits maybe the Thousand Sons on it only does so because they also have their hubris to prevent this from becoming one-sided.
Pushing the story for Lorgar or the Night Lords just cheapens everything that actually gave them texture before.
