You could start by engaging and reaching out. For example, assuming someone doesn't care because of their race, gender identity and job is kinda shitty. Maybe look into those internal biases.
The next part would be finding out how they are and will be effected by this new presidency. Sometimes people have a hard time caring about a problem if it doesn't affect them directly. You might have to get to know your coworkers rather than make assumptions about them to learn this.
Being polite and nice to them also helps, no one wants to hear from someone who's screaming at them.
