Pink returned to the pop world in August with her single, What About Us, which she says was inspired in part by the state of current world politics.
She released her sixth album, The Truth About Love in 2012, when Barack Obama was the US president.
Her seventh, Beautiful Trauma, is released in October among political unrest in America and across the world.
But as an artist who has recorded anthems for underdogs throughout her career with hits such as Don't Let Me Get Me, Raise Your Glass and So What, she says she is still fighting "an old fight."
"I've been marching on Washington since I was three years old with my dad," she tells Newsbeat.
"I'm a feminist and I believe in equality and I believe in banishing racism and homophobia and sexism and all the isms but we have always been the underdog.
"That line of thought has always been fought. It's an old fight and they're never going to win because we're not going anywhere.
"So you can even have peace and accept it or you can continue to be an idiot."
In 2006 Pink took direct aim at the then-president George Bush in her song Dear Mr President, but she plans no such attack on the Donald Trump.
"There are no words for that guy," she says.
But it's not just global politics that concerns this superstar.
During her 17-year pop career, Pink says one of the worst things she has seen emerge is fierce rivalries between female stars and their devoted fan bases.
In August, she performed and gave an emotional speech at the MTV VMAs where all eyes were on Katy Perry and Taylor Swift.
Katy performed her diss-track Swish Swish while Taylor premiered the video for her revenge track, Look What You Made Me Do, at the ceremony.
But Pink has no time for rivalries and wants to see more support for women in pop.
"Music is a big enough platform where everybody can win at the same time so why not support your fellow females," she tells Newsbeat.
"Why not support the people who are fighting the good fight for you?"
Pink famously clashed with Christina Aguilera when they covered Lady Marmalade in 2001 over who would sing which part, but the 37-year-old mum of two put that rivalry to rest a long time ago.
"I think Christina is incredibly talented, we've had our **** but it's done," she says.
She also wants to see more support and less rivalry between fans of the artists.
"When I was growing up I listened to all kinds of people, there weren't these groups of fans that were attacking everyone else's fan bases.
"It's very catty and very snarky.
"Honestly I'm just so tired of the snarkiness."
