I'd argue that touch without consent should extend to all humans, no?
I think this whole touching thing (of all humans) is a tad more nuanced though than a yes or no, and if we are not careful enough, we'll end up having a society that is unable to have organic human interactions.
I'll give you an example. Two separate first dates with two different people. On one date, my date lost interest in me exactly because as she put it "I wasn't man enough" to just pin her to the wall and kiss her when I felt like it. I was, but the consent thing stopped me. I explained it to her and she literally said "you don't ask a woman if you can kiss her or not".
The other date, I asked her at the end of the date if I could kiss her and she said yes, but it felt like there was a bit of a disconnect in the moment as it happened. She even seemed a little surprised. So there's that.
I also think the article isn't cognisant of just how wildely different cultures and customs can be. In Eastern Europe it is still pretty common to kiss people of the opposite sex on the cheek when saying hello, goodbye or thanking someone.
Touching is a far bigger topic than this article, or any one article could cover, but I think - as with everything - we all need to be careful how far we take things. If suddenly patting someone on the back for doing a good job becomes a touching without consent situation, that's when I'd say we have gone too far.
