well yes, but the Blood Ravens seem to constantly piss them off, maybe because no one knows where they came from, some say they come from the Thousand Sons legion, another reason why the Inquisition hates them

I feel that since CSM are Undivided, we should categorize them based on the legions. I feel like Iron Warriors will be bro-tier, Black Legion will be edgelords and Word Bearers will be a tossed bag of bros, neckbeards and edgelords. If Night Lords get in, they'll be Donte-tier edgelords, dwarfing even the Black Legion with their edge. Alpha Legion will be a bunch ironic xxMetalxxGearxx420's, for better or for worse.

So they will run around and scream "F*** you" out of their lungs?

Yeah, with bat wings attached to their heads

This is so edgy I cut myself on the thought alone.

I expect space marines to dominate because they have biggest fanbase that i have seen.

Indeed, mainly because Space Marines are seen as protagonists of the Warhammer 40k Universe

the Space Marines aren't exactly the "good guys" all of the time, and i think that the IG doesn't get enough respect as they deserve, its hard holding off the enemy until the SM's get there to take all the credit

They will always have a special place in my heart ^.^

All this is pointless as Eldar shall once again dominate the galaxy as Ynnead is grows stronger.
