The term holocaust has been used to describe nuclear war countless times in the past 20+ years and no one has lost their minds over news reporters saying "Nuclear holocaust"
You are looking for reasons to be offended. The guild name in no way offends and never once did I look at the name and think anything other than the definition of holocaust... never even considered the Jewish race/religion when seeing the tag.... and I hate <Holocaust> (well I hate zergs)
Taking offense to that is stupid. <Holocaust> is no different than <Annihilation>, <Obliteration> <Decimation> etc to me... but I'm educated beyond the 4th grade and reading Elie Weisel's "Night" so I've seen the word used to describe many more events than THE Holocaust.
If they can say it on the news without referencing THE Holocaust, and no one loses their minds.... you are probably just being a giant gaping sandy vagina. When the FCC is being less sensitive than you.... you lose ALL man cards. Instantly. Forever.
