Nah. This isn't that. It's bullshit, it's unnecessarily cruel, but "get a new ID with the M or F switched to the one you don't identify with" isn't all that relevant to SAVE when either way that ID alone wouldn't qualify as documentary proof of United States citizenship per SAVE. If you're already taking time out to go to the DMV though, you may as well get what you were already going to need to meet SAVE while you're out and dealing with government bureaucrats. See this as an excuse to get the other sorted too.

Seriously though, everyone needs to read SAVE and ensure you have what you need. Do it now, don't wait until the election. Don't even wait until SAVE passes. Be prepared for what they want to pull before they succeed at pulling it, because after they're only going to make it harder.
