President Donald Trump’s move to the White House on Friday (20) has proven to be pretty polarizing, to put it mildly. This past Saturday, millions of people around the world expressed their beliefs by participating in the Women’s March. Celebrities and musicians including Alice In Chains drummer Sean Kinney, Pearl Jam guitarist Mike McCready, Frances Bean Cobain, Madonna and many more participated.

While many didn’t actually march, some musicians took to social media to offer their opinions on the state of the world. Metallica guitarist Kirk Hammett  was among them, and he made a handful of Twitter updates concerning his thoughts on recent happenings.
