PotD can be effective, but only if enough conditions get bad enough for the majority of people are hurting bad enough. The pressure has to be built-up to the point that the normally "I'm not a political person" types have personally been fucked over badly enough. Otherwise they are able to be kept in line by corpo propaganda about how "evil" the person(s) are for being violent. Law and order and all that.
Anyone who said "nothing will come of this" has been proven wrong, infinitely so when you, yknow, think about how propaganda works and realize 90% of the country simultaneously going "yea yknow what kill those fuckers" is obviously in and of itself something momentous
If there are copycats, it still needs to be shown that it actually is effective in terms of political change. Likewise, if change does happen in the near future, it would be unclear whether it was already in the course of its own development with or without Luigi
I dunno, I want to see if it continues past the next week or two. There have been a decent number of times where it felt like there was some meaningful change coming and then people just forgot about it.
Of course, big things do happen, but sometimes it feels like a phenomenon that happens exclusively outside America.
