It's the same twitter account she used to "shame" the two guys who made the joke. It's relevant.
Just because I send two emails from my Gmail account doesn't mean they are related and/or relevant.
penis jokes on twitter = OK
penis jokes behind me in public = BAD
It's nice that all of the sudden "pycon" is a "professional event" as if people are all walking around in suits and ties and monocoles.
Plenty of people go to conferences with friends as social events. Pycon is definitely like that for a lot of folks. That's why it's billed as an "annual gathering for the community".
Talking privately in hushed tones at a conference you treat as a social event is, IMHO, much better than blaring it out publicly to 11,210 followers.
I believe you're in the wrong room sir, that would be the Steampunk convention down the hall.
Also, the context is very different. You may think of PyCon as a social gathering, but it is in fact work-related for a lot of people (including, presumably, Adria in her role as a developer evangelist). What's acceptable in an informal, personal setting (e.g. jokes made to people who explicitly chose to view her personal twitter stream) may not be acceptable in any kind of professional setting.
The real problem is that she took what could have been a simple case of "inappropriate but dealt with" to a completely different and public level.
I'm not even commenting on whether either gender _should_ have such a monopoly (they shouldn't in my view). But just in actual fact it is not so in our society today.
Do you know what a developer evangelist is or even what is expected of someone taking a representative role at a company? I don't know what this has to do with sending two letters from gmail. Sounds like argument from irrationality or grotesquely inappropriate analogy.
