Internet users and news outlets have speculated that the sperm cups are aimed at Democratic Vice Presidential candidate Tim Walz and his wife's infertility issues. The Walz's had their children using in vitro fertilization (IVF).
The cups therefore could be a way to champion Vance's natural ability to have children. However, many Americans (regardless of political affiliation) struggle with infertility and use IVF.
Despite being humorous, it's currently unknown if the J.D. Vance cup photos are real. For one, the original X user that posted them, @UsaCamy, has a profile that's raised suspicions among many, as pointed out by X user @elisethoma5.
So basically, if this turns out to be a real thing, then they're dunking on people who want to have kids but have infertility issues. Which ... that's just kind of a ridiculously petty thing to do.
I've said it before and I'll say it again: right when the MAGAts seem to have reached yet another limit of human stupidity, they find another new and unexpected way to be complete and utter fuckwits.
Sadly it's true, though it seems to be limited to just the people in that group. Something to do with JD Vance/ James David Hamel / James Donald Bowman (lots of names in his history!) comments about childless Democrats.
