Another wild fire started by another gender reveal party has opened up the whole can of gender worms. Not that it was ever really closed. And no one seems to be focusing on the real issue. So I'm dusting off the ole soap box.
1. Any celebration can lead to injury or even disaster if the celebrants are careless. I'm sure people have been injured and even killed at birthday parties or holiday celebrations, but try telling people to ban those and see how far it gets you. Letting unqualified people handle (or build) pyrotechnics for any reason is downright foolish, and that's what causes things like wild fires and homemade pipe bombs.
2. Social Media is no more to blame for people showing off than a skateboard or a sports car. The people who are impressed by whatever the stunt might be are not to blame. The person showing off chose to do it, and are therefore responsible for any damage done. It's no different than "Billy dared me."
3. Yes, people do care what sex someone's baby is. Family and friends do, and for celebrities of all stripes, the fans do. For one thing, knowing that fact makes gift shopping much easier. If you want to complain about people being gendered before birth, refer to my next point.
4. "Gender" has also become the polite term for the biological fact, which is why Sex Reveal Parties aren't causing wild fires, and that does confuse the issue. If I announce the child in my womb has a penis and testicles, all that means is that his biological sex is male. Stating a biological fact is not gendering. Dividing toy departments by the sex of the child is gendering. Telling a male child he can't wear pink is gendering.
5. Often the decor is quite gendered at these parties. (Imagine what these parties would look like if decor stuck to biology!) Cakes say things like "Tiaras or trucks" and "Glitter or guns". Pink and blue everything is everywhere. Parents who take those stereotypes to heart are going to have more impact on the child than a party that happens before birth. Parents who are having fun with it, just for the day? Not so much.
6. No one is hurting you by having, or not having, a party to announce the sex of their child. At least not if they do it responsibly. If you feel these parties are morally wrong, don't attend. I don't go to drunken orgies for just that reason.
Back to the original point. People are losing their homes and lives while we bicker over sex and gendering. If you must be negative, blame the careless, not the thing they were celebrating.
