>>Is this concerning or just laughable?
It's a little concerning that the the OP considers overt objectification and sexualisation of women to be something which should be defended.
Exactly.
Even in the OP, a list of suggestions is presented -- "eight things developers can do to make games less shitty for women" -- and the response is to decide whether the list is (A) concerning or (B) laughable.
Let's see...
Option A) you find the idea of reducing unnecessary sexualisation, and an increase in diversity of lead characters to include all genders, sexualities and races to be concerning. This is such an irrational fear that it's hard where to know to begin trying to calm it... If in this camp you're going to go down in history with the people who campaigned against universal suffrage, interracial marriage, or gay rights...
Option B) you think the list of suggestions is laughable. The very idea that sexism either exists or is an issue is an issue that anyone would bother discussing at an academic level, is a complete joke to you. Every item on the list is a joke to you, so as far as you're concerned there's no point in having a discussion about these points, ever.
There's not much to say about this choice, other than you're either extremely ignorant or bigoted, or both. Seriously, it's just plain nasty.
The lack of an "option C" is extremely concerning, as it exposes nasty worldview of the bigot.
Imagine if someone started a thread saying:
"Person X had suggested that gays should be able to marry. Is this view concerning, or just laughable?"...
Or:
"Person Y has pointed out that most films fail the Bechdel test, and they've posted a list of suggestions to improve the situation. Should I be concerned by these views, or just laugh at their stupidity?"
It's just horrible. Stop being so horrible to people. You need to realise that this kind of behaviour is actually abhorrent.
Try discussing people's ideas instead of brushing the off as being a joke to you while simultaneously demonising them.
