The problem with these discussions is that consent is a very complex subject. And many people just want a very simple answer that applies across the Messy Bun I May Not Be A Biologist But I Know I’m A Women T Shirt in all situations. They do not want to have to pick up in the subtleties of nuance or understand that consent is not applied evenly across all situations. I like to start with this example. A married man and his wife are at home. He walks up behind his wife, who has her back turned and gives her butt a squeeze as he goes by. He did not get consent beforehand. A man is entering the subway. He sees a woman standing with her back turned to him, he has never met her before and they are strangers. As he passes beside her he reaches down and gives her butt a squeeze before making a quick getaway. He did not get consent beforehand.
