(from http://geekfeminism.wikia.com/wiki/Sexualized_environment)
* In geek contexts, they are usually a way for heterosexual men to bond over their common attraction to women. This is othering for anyone who is not a heterosexual man, including, obviously, women, and contributes to their invisibility in the field. This sensation of exclusion is very visceral when in a small minority, as women can be in geek settings.
* There is a long tradition of sexual images, suggestions and approaches being used to shame, scare, harrass or brutalise women. This is common enough that most women will have had personal experience of it. Therefore many women are unable to sensibly assume good faith on the part of unknown men seeking to make a situation sexual and feel mentally uncomfortable at best and physically intimidated often.
* While in many areas this restriction is loosening, women are stigmatised as well as celebrated for being too sexual. This traps women into a double bind when responding to sexualized environments, because even by getting the joke they may reveal themselves as too sexual.
Keep in mind the commenter received extra points for this.

I am happy that people here in the Netherlands are so much more tolerant when it comes down to things like sexuality, public intimicy and nudity. It seems to me that in the US people get offended very easily and want to limit another persons freedom of expression just so that they can be offended a little bit less.
The image is so famous that Lena herself was invited as a guest to ICIP 2015 and chaired the best paper award. I think she also gave a talk. I dare say she doesn't have a problem with it.
Except, you know, for bisexual men and women, lesbians, heterosexual trans-men, and so on. A lot of people could theoretically bond with one-another over a shared attraction to a given gender. (Not making any point to the spirit of your argument; just poking at the letter of it in hope that you refine it.)
