How so? Aside from the wholse social conventions around gender, we do physically fit into either female or male in the vast majority. So why is it offensive to ask people to pick a gender? What's the big deal?
they removed the option not to specify and then got really nasty with some people who called them out on it. It's messed that they were trying to force people into gender binaries when so many people don't identify within them. Calling someone a hermaphrodite because they have a non-binary identifying gender is sort of incredibly hateful. For cisgender people this probably doesn't matter so much but its really horrible to have your gender expression dictated and restricted by someone who isn't you.
