Oy. What a loaded topic! Dub-con is sooooo gray but under most circumstances, I'm perfectly cool with it. Non-com? Just not my thang. I avoid it for the most part, unless it's an important plot-point AND done behind closed doors.

I've got nothing new to add to the conversation except that I agree with the 'better safe than sorry' mantra. Kinda sounds like if there's even a ghost of a chance that an encounter isn't perfectly consensual, label it dub-con to be on the safe side. Not sure it's necessary to gray-out warnings, however. If you can't even look sideways at the mere mention of a particular word, you need to avert your eyes from 90% of life. They're simply words, devoid of context. No one likes the word 'cancer' but you'll have to read it every now and again.

My two cents!
