That's just taking things to the completely opposite extreme, though. It's not treating them like human beings again, but like priceless art exhibits that can't even be approached.
That is a very interesting point of view. It begs comment on the growing discontent of men that woman are so protected that men lose all presumption of innocence - their right to due process - which, by the way, puts women on an even higher pedestal and causes men to avoid them for fear of recrimination and accusation. It basically means the bad guys will keep at it while the good guys are losing the will to try any more.
The risk is too high.
The risk of of what, though? Being "shot down?" Believe me, there was a time in my life when I was scared to death that my interests/advances would not be welcome. But, well, that was
my insecurity and issues I had to deal with.
Otherwise, if you see someone you're attracted to, smile at them, they smile back, you introduce yourself, show an interest in getting to know that other person as, well, you know, a
person, then there's no risk that involves anything close to (or as melodramatic as) "presumption of innocence."
And if the attraction is mutual and events progress far enough, it's not going to break the mood to ask for a definitive consent before proceeding toward anything close to needing a presumption of innocence.
In fact, why would you (or I) be engaging in any activity where such presumption would be necessary? Instead of presuming (or assuming) consent, take a moment and make sure it's explicit. That doesn't place anyone on a pedestal, but rather makes sure that everyone is being treated as, well, an actual person, rather than merely an object of desire/lust, etc.
