Which is a thing that doesn't happen. The few late term abortions that occur for reasons other than health issues result from a lack of access to the procedure in the early term (i.e. due to Republican gatekeeping by requiring things like letters of medical necessity, limited numbers of providers, et cetera), and even then those skirt the edge of viability anyway.
The idea that viable babies in the third trimester are being terminated because lulz is a conservative fiction.
