Replying to International Women's Day

So today is International Women's Day! Women are encouraged to not go to work, wear red, and avoid shopping. Everything im reading has those three things as what women all over the world should do today.

Can someome please explain to me why women are being encouraged not to shop? I mean I get the idea that they're trying to show women's economic impact by not shopping, but seriously, doesnt that seem a bit patronizing? Like one of the two things to show your impact, shopping? Way to play into a sterotype and make people think all women can do is work and shop.

Yay 2017!
