It was already illegal to have sex with unconscious or drunk people (even mildly tipsy people, in fact, although in practice no one ever reported such things).
As such, this law is unnecessary.
Additionally, I do think this will result in lots of frivolous rape accusations. The intersectionalist left is already obsessed with "close reading" every aspect of society to find a sinister "White cis-male" motivation behind everything. Now they want to do that with sexuality in the legal sphere. It's unpopular to say but I really do believe there are a lot of misguided women who would allow themselves to get "raped" rather than just say "no" even though saying "no" would likely stop many of the "rapists" Because if they said "no" and the guy did stop, then they wouldn't be able to complain about the omnipresent "rape culture"
Oh. My. God. You have got to be kidding. You are literally defending rapists. Oh my god.
