Those kids will have to be exposed to the world eventually (... r-right?). Converting them to help spread love based on empathy and morals rather than rhetoric seems like the fastest route in my head. Fight fascist propaganda with our own~
However, idk how to reach them lol. Memes n pray? XD
A lot, I'm finding, but it can be summed well with: I wouldn't redo my life, I'd treat this as an extension. I'd attempt to push my family towards less destructive tendencies, try to find and comfort my future-friends, and maybe try to guide my city towards a more productive future.
Not much truly changes other than my access to more time and power. My reality will still consist of the traumas I've experienced and having a chance to change the events will never make what I've experienced go away. Still way better than now, though!
