@Wuzzy No this is important.
I want to understand what you mean with "consent is not a spectrum".
This would explain it. If you're not considering what a person actually wants in the question of consent, then yes, I agree, there can be a hard red line between consent and no consent.*
But not considering what people want when it comes to consent is imo batshit crazy, absolutely dangerous and will always lead to people getting hurt.
*PS: No, actually I still don't. It's still only possible for the person giving or not giving consent to draw that line.
