Changing this to appease the internet censors will be a slippery slope that will curb your creative freedom to write stories as you see fit and prevent you from exploring any themes that might be "offensive" to someone, somewhere on the planet. Say goodbye to dark, mature themes in your games, for instance, lest we might anger the perpetually angry.
It's worth noting the double standards of some of the people involved in requesting the excision of this content, especially the very person who first started this:

"It's a joke when we say it, but don't you dare include it in a work of fiction that, by no means, shows the author endorses the behavior of any of the characters!"
I don't like any of the backer content myself, as I find it varies wildly in quality (more often than not falling into the fanfic territory), but I'd rather not tailor the game to suit me since I know some people out there enjoy it.
One thing I would be all for is a toggle to turn off all backer content in the options menu, but this is something that will very likely be modded anyway at some point.
