In all honesty it's likely that the 47% of white women who voted Hillary have little to no social contact with the 53% of white women who voted Trump. It's not entirely clear to me what this line of argument is meant to accomplish.
This is what annoys me, as a white woman who currently lives in the OC, I don't run in typical republican voter circles at all. The only people I talk to day to day that could have possibly voted for Trump are other gamers online. Also that a big chunk of the people I know who went to the DC march were from various places in MD and NOVA, which are heavily democratic locations.
We personally didn't have any negative interactions at the march, or on the trains to and from DC. Even the non--marching DC residents we talked to were happy that so many people were there to stand up for everyone's rights.
We did have some random white dude with a flag yelling "God Bless Trump", who just got random eyerolls from all the ladies walking past him. But that was way outside the March near Chinatown Metro.
