AITA for jumping out of the way when my niece and nephew tried to push me into a pool? (Full Post)

Happened today.
My folks decided to host a barbeque because I guess that's what older people do. I declined because I really don't like my two sisters, their husbands or their kids (wife and I are child free). Mom then pressured the wife. Long story short, we went.
By the time we arrived there were about 20 people there. My sisters and their husbands were already solidly buzzed. Drunk really. My mom was spending 100% of her time trying to keep the nieces & nephews (ages 7 to 11) more or less under control. My dad had strategically retreated to the whirlpool part of the pool with small cooler full of beers. Wife and I made small talk with miscellaneous people, ate food and had a frozen margarita. Sisters/BILs took turns criticizing us for being late, not being in our swimsuits and screwing up the vibe. Whatever. Typical suburban summer get together.
About 45 minutes in two of the kids ran at one of the neighbor guests who was standing next to the pool and pushed her in. She was at the pool steps, stumbled in but didn't fall so only got half wet. She was clearly very unhappy about it but she didn't make a scene, just went over to where the parents were, grabbed their towels, dried herself off and left. Sisters and BILs thought it was all great fun.
A bit later I was standing a few feet away from the pool chatting away with someone. I saw three of the kids running full tilt at me from the corner of my eye. Obviously I was next. Not that it's terribly difficult to outwit young kids but I just jumped out of their way at the last second. All three of them ran straight into the pool at full speed. Most of the other guests (including my wife and me) started laughing but their moms - who as I mentioned were pretty shitfaced - absolutely freaked out. Apparently two of the kids couldn't swim even though they were in swimsuits. Since I wasn't in swim gear I stepped back from the pool and let other people fish the kids out. The kids were bawling their heads off like they'd lost a limb.
At that point all hell broke loose. The four drunk parents were yelling at everyone in general and me in particular for "nearly letting their kids drown" and also because two of the kids had been videoing the trick using their parents' iPhones, which were now at the bottom of the pool. One of my BILs got into the pool to try to retrieve the phones but his BMI and BAC made that impossible. No one else volunteered to help, unsurprising given that my sisters were still bitching at everyone.
I told my sisters it was their job to watch the their kids and that if anything had happened to them it would have been their responsibility not mine. There were some pretty strong words on both sides. Wife and I left after the other BIL fell over and face planted while yelling at us. Now they're saying I should have let the little shits knock me into the pool and have their fun (and ruin my phone). So... AITA?
Side note: Dad, of course, never got out of the whirlpool.
