Show me a culture that likes to recognize the war crimes they commited as war crimes.
The Japanese seem to do way more of sweeping their dirty laundry under the rug from WWII under the rug than Americans.
And no, that’s not trying to excuse Americans of acknowledging their own war crimes. Every culture should own their past and do their best to learn from their mistakes.
You’re correct that it isn’t as good of an alternative as flossing but you’re meant to do both.
You should floss, preferably with actual floss and not a pick, and then follow that up with water irrigation. You dislodge food and break up the plaque with the floss and flush it out with the water flosser.
