I honestly do not think that JD Vance wants to do things to harm childless adults, nor do I think he wants to unduly benefit parents over non-parents.
However, he sure does do quite a bit to add fuel to the fire of the leftist conspiracy nuts who are saying that JD hates childless people and wants to give them fewer rights/freedoms/benefits.
It would be super great for the GOP if he profusely apologized and/or shut the eff up.
