These are not the things you truly teach to the next generations. There's is always a filter on what you want them to see. That's where you failed. The young one's know how to ask their elders like their uncles/aunts, parents grandparents where they trust on what happened on their time to verify what the politicians said about their opponents. And that's where BBM got his votes from the young voters. You probably won't believe it and I don't really care since people like you who are self righteous won't see it the other way and its the same reason you will keep loosing elections.
Toxicity is always part your campaign and many voters don't like that. Look at what Trump is experiencing now, he has more chance winning the next election than in 2020.
