There's a man who's the human embodiment of hate who's going to become our next president, so the best thing we can do is try to connect with people who are representing love and connection. On the subway ride here, everyone was just extremely tense and there was this crazy air -- so dark -- and if that's the result of our presidential election, something has to happen, don't know what the next steps are yet but I'm here to support the people around me.

At a second New York City demonstration, people chanted: "Donald Trump, go away, racist, sexist, anti-gay."

There were also walkouts and "Not My President" protests by high school and college students in California, Iowa, Arizona and Washington, reports the Independent.

Berenabas Lukas, a 15-year-old student at Berkeley High School in California, told the news site: "I feel very disgusted at America," and added that it was difficult "to see that your life isn't valued as an African-American teen. [Having] a president that doesn't support Latinos or African Americans, who is racist, and who is going to run America for four years, maybe eight, is sickening."

College students protested at the University of California, Los Angeles, Irvine and Davis, and at California State University, San Jose, while high school students protested in Phoenix and Seattle (videos below).

The Seattle students marched downtown and shouted, "He is a racist," and "Not my president!"
