If she really did use a milk pump right there at the table, I don’t see any difference (as you point out) between that and the men there saying, “OK, excuse me now while I whoop this out.” and then urinating into gallon milk jugs, or whatever Hammacher Schlemmer sells that big bucks scheissers would feel worthy of accepting their pee.
They want to be ridiculous, we’ll ridicule them, right? (Alinsky rule #5. We read your book you POS!)
If I remember, breast pumping is about every 3 to 4 hours, there is no way she could not have scheduled this on her own timing and no need to even mention you have to breast pump.
In the 90s in NYC, there WAS a trend for women to breastfeed in public. No cloth over the breast but whipping it out in public and daring anyone to say anything. I can still remember working for a lib company (which turned me conservative) and seeing working mummies breastfeeding, pumping and then dumping their infants on their secretaries to “take a meeting.” What a turnoff it was. So I totally get Trump’s outrage. He was luckier than me - he had the power to shout at her.
