On a scale between 10-10, with 10 being the most useless load of rubbish ever created, how dumb are gender reveal parties?

I mean.. they can be obnoxious i guess. But any party can be obnoxious. Unless they're causing harm with it i don't see why it would be any worse than a birthday or any other celebration

You get tons of birthdays, some people take learning if they're having a son or daughter more seriously
