@engineer,
Of course it's political.
You start with a slogan, "#MeToo", or "United We Stand", or "Support the Troops". Almost all Americans agree with broad slogans such as these. But then, people attach political meanings to them.
In this thread, made up of mostly progressive men, we have had statements about the need for censorship and rape statistics on campus. These aren't directly related with sexual harassment in the workplace (or supporting our troops for that matter). These are political issues that many Americans disagree about.
Once you get past the slogan... the issues are deeply divided along partisan lines. Your political stances have much more to do with how you feel about these issues than your gender.
You agree with progressive men. You disagree, dismiss and ignore conservative women on these issue. The polling shows that the divide is along partisan lines, with men and women on both sides.
Viral campaigns on Facebook are political in general. Facebook provides a great way to send out political messages wrapped in clever slogans in a way to make the general public receptive to them. Confirmation bias is a powerful political tool.
Everyone wants to say "it's not political when I'm right".
