Trump ran or considered running for President some two or three times, before 2016. Marx wrote his book, between 1867 and 1894, but the Germans stuck with capitalism and it was decades before the Communists took over in Russia, under different leadership. Most singers don’t become Taylor Swift.
For any particular thing, there’s a right time, place, and message for it to become a movement.
I have no idea whether this is that time or the message but, I’d guess, Taylor Swift fans didn’t approach the question of whether she’d one day be a mega-star by telling each other, “No, that’s not realistic. It’s I-M-P-O-S-S-I-B-L-E.” They just said, “Yep, she’s amazing. You should listen to her.”
If something is good and you’re not promoting it, then you’re overthinking the issue.
