Ultimately, Suvi was offended because she wanted to be. The whole time she cited cissexism (a cisgender person is more or less the opposite of a transgender person). She clearly has issues with gender roles, and is likely one of the people who would like to see the gender binary eliminated. Something like this logo does kind of further the "women like women things" mentality, but it's really not that big a deal. Women who like women things have every right to be open and respected about their beliefs as women who like men things and men who like women things.
People like her who avidly fight the gender binary have a noble goal of mutual acceptance in mind, but they don't realize that by denouncing things like this, she's just as bad as those who would persecute her beliefs. The way to acceptance isn't through the suppression of the current status quo, which is what she wants. You can't fight fire with fire, and all that.
This got long. Sorry about that. It is a nice logo, by the way. Like others have said, it conveys its intended message simply and effectively.
