I've read there was a 2017 Women's March held on the day after President Trump's inauguration in Washington.
It's not clear to me why? What's their motivation? And what goals do they hope to accomplish?
According to Wikipedia, their Goals are as follows:
Protection of our rights, our safety, our health, and our families – recognizing that our vibrant and diverse communities are the strength of our country
Their reason for marching was to raise awareness.
The 2017 Women's Marches were a series of political rallies that took place in cities around the world since January 21, 2017, with the goal of promoting women's rights, immigration reform, and health care reform; to counter Islamophobia, rape culture, and LGBTQ abuse; and to address racial inequities (e.g., Black Lives Matter), workers' issues, and environmental issues. The rallies largely targeted Donald Trump, the recently-inaugurated President of the United States, as well as many of his statements and positions which had been deemed anti-women or otherwise reprehensible
i.e. it can be viewed as a protest against Trump's quick removal of any mentions on LGBT rights on the US. Govt. official website, www.usa.govt. One can assume that it comes as a reaction to him being elected President, even if he is a self-proclaimed women-groper. You can read and watch on several sites, here is the first google result:
Whether you agree with their cause or not, they have every right to express themselves, just like you do.
According to their website - as seen here: https://www.womensmarch.com/mission/ - they say,
In the spirit of democracy and honoring the champions of human rights, dignity, and justice who have come before us, we join in diversity to show our presence in numbers too great to ignore. The Women’s March on Washington will send a bold message to our new government on their first day in office, and to the world that women's rights are human rights. We stand together, recognizing that defending the most marginalized among us is defending all of us.
Interesting to note is they claim to be for all women but made this tweet - https://twitter.com/womensmarch/status/821112766052401153/photo/1?ref_src=twsrc%5Etfw - after barring a women's group who didn't comply with their political platform. Reading the Twitter thread shows they removed other groups who also didn't agree with their entire political platform so their stated goals of the march may be in question.
