hum most of the 40k people i know like manga (tho i don't care for it my self)A random person said:Anime bashing, as anyone can tell from my reactions to it and my posts in the anime fans group. Especially if it's unprovoked bashing like a certain person I dealt with recently.
Also, gangstas, dumb Warhammer40k fans (partly for the above reason), and internet tough guys/people who attack anything odd out of some normality/coolness fixation (also that person I dealt with recently).
the think i hate are people that hate 40k and don't know crap about it
