Never stop reminding them of those stupid pink vagina hats.
I'm not sure it's fair to conflate Women's March participants with Russiagaters, although there's no doubt a big overlap. I think the pussy hat phenomenon was a reaction against an elected president who appeared to be a womanizer and possibly a misogynist.
Also, I think encouraging people to forever ridicule other people (even shitty journalists) for their mistakes is a bit cruel.
