I don't think it's a shame to discuss art in any way, I think discussions like this are always good to have around a piece of art as they promote understanding of others views and understanding of art.
I wouldn't say that I'm hypersensitive, but I work a lot with how genders are portrayed in art and of course that perspective is always close at heart when I view artworks. That's the beauty of art, that we all see it differently.
To me it doesn't matter which gender the chocking hands belong to, the point is that the subject, who is female (like 97% of all people portrayed in art - something to ponder) is being portrayed both in a sexualised (ie sexy - I didn't know the word sexualised didn't exist in English) way while being abused (choked). In a world where sexual violence against women is so common I think it is necessary to contextualise this and examine how we portray women in art (as we mostly do). This painting is not an isolated incident, women are portrayed as weak and inferior, objects to behold, in the majority of art. Women are painted from the perspective of a heterosexual man, and are thus made to be enjoyed. I believe that we need to understand and examine this, and the effect it has on the viewer and in the long run, our society. Art is both a reflection of what is and a way to affect what is to come, and I believe that as an artist one has to be aware of that.
If the painting is meant as an erotic piece I think it's a bit disturbing that the subject is being choked - if it pertained to a special fetish or sexual interest I would have liked that to be expressed from the artists side. I am myself interested in BDSM and can see how this would be attractive for some, but I hardly think all people who have commented on, liked or even viewed this without any reaction on the motif are interested in BDSM or sexual asphyxiation. That is what I find disturbing, that so many view this way of portraying women in a weak and sexual way in the same time as something normal.
