Note that propaganda is just one tool in the toolkit.
Active silencing, de-platforming, censorship, de-monetizing, doxxing and many forms of cancellation are other tools.
Younger folks are catching on that bad acts means bad actors.
The shutting down of protests on college campuses and deporting people who criticized Israel has helped turn a whole generation against them. Zionists don’t seem to understand that the more aggressive they go after people the more enemies they are making. Even many younger Jews are backing away from Zionism. Netanyahu basically screwed the pooch when he brutally bombed all those civilian areas killing scores of innocent women and children. No amount of propaganda will make this go away.
