Jokes aside, it's not the most difficult thing in the world for the police to track down a sender in the absence of a return address. There can be some security through obscurity but these days it's not nearly as easy to do this as it was 20 years ago, thanks to a number of new factors. Doing this to a nobody and getting away with it is one thing but doing to to a VP candidate is going to have LEOs pulling all the stops to ID you. There's no shortage of people who don't understand this and are shocked when their door gets banged on or kicked in at 3am.
People like JD Vance only respond to might making right. You can talk shit, and kill his ideas, logically until you die. he won't be swayed, even in the slightest. Fascists respond to fascism because it is an inherently violent ideology that they believe will allow them to enforce violence on people they don't like. That is is their language, violence, including shows of "strength" that show you can enact, and enforce, said violence. Things that truly call this into question, being bullied, being on the losing end of violence, and otherwise being made to look "weak" publicly, actually do damage their position within their fascist group because they show that the outsiders are stronger than this person.
Aside from getting your ass in jail (Still amazing that someone can take part in an attempted coup and not only not serve time, but actually run for office despite how clear The Constitution is about the subject, while mailing cat litter has a real chance of causing you larger legal problems. But I digress), you are just kind of fucking up the work day for the poor slobs who have to go through his mail.
I know this is a meme, but considering he is a VP nominee, I'm sure the FBI is gonna be keeping tabs on him, and unfortunately mailing someone used kitty litter is an act that falls legally under "domestic bioterorism". It's the same reason that if (you can prove) a worker spit in your food at a restaurant, they get a cushy room in a federal prison.
I support every bit of sentiment from this post, but don't make yourself a felon (both adding to the workforce of legal slavery, and denying yourself the chance to vote against this turd).
I missed what he has to do with used cat litter. Can someone enlighten those of us that aren't caught up?
Also, at the risk of being a killjoy, wouldn't the package have to be marked as a biohazard? I'm not sure it would make it through screening to get to him. A lot of loose pet hair from shedding would be cheaper to ship and get everywhere.
