Hugos are science fiction and fantasy.
I think perhaps the origin of these problems might result from these associations having been created with the intent to be for everyone and open to all opinions. That might not have been a problem 40 or 50 years ago when there was a more common common consensus of what is appropriate in fiction and anyone who was crossing those boundaries didn't even have to bother showing their faces. Then over time you have new people coming in with ever more diverse opinions and views, and eventually you have silent minorities feel they have become silent majorities and start to openly speak their minds. This comes as a great surprise to people had not noticed the winds having turned and bam: drama.
