So Dobson's angry that the artist on Twitter didn't tag him, but in the past he's complained about people talking about him without his permission. Which is it, Dobson?
Of course it's neither - Dobson wants to pretend he's open to criticism as long as it meets some kind of objective standard, but we all know that he just changes his standards so whatever criticism he receives doesn't meet them. He would not be able to provide an example, either theoretical or concrete, of "good" criticism even if he wanted to.
Is this supposed to be empowering to women, is it supposed to make fun of people who join the navy, is it supposed to be uplifting and get you in a mood to get shit done?
I don't get it.
He's criticising the original poster because it's saying that women can't join the Navy in WW2. Which was true, and sexist (personally I'd prefer women didn't choose to demonstrate their equality by enforcing US foreign policy with violence, but YMMV). While it's not that realistic to expect the US government to produce a poster critiquing the sexism of its own policy, that doesn't change the fact that the poster addresses something that's plainly sexist and doesn't mention it. Which is pretty shit.
However! For all Dobson's criticism of the US military's exclusion of women might be admirable (certainly in comparison to other manifestations of his feminism, which mostly revolve around pop culture and fappable lesbians), his reworking doesn't actually address them. "Hey women, if you want to get into a field you're excluded from due to gender, have a sex change!" is fucking terrible advice, even from the rosiest possible perspective on transgender rights. It's like telling gay people to turn straight if they want to get married.
It's possible that he didn't intend his reworking to be a correction of what's wrong in the original version so much as a total change of subject, but that means that he loses any credit he gets for criticising the original sexism.
So, overall, once again, Dobson shows he has no real understanding of politics and is just trying to get attention from SJW-y types. Unfortunately even your average SJW has a better understanding of gender politics than Dobbie displays here - they at least generally get that if you're going to criticise something for being sexist, your alternative should address the sexism, no matter how idiotic, ludicrous or scarily authoritarian it might be.
