If this is a high priority for you, have you personally dissociated yourself from people who hold views similar to Thiel's? Friends? Family? Coworkers? Employees? Employers? Business partners? Customers?

Sam Altman and Paul Graham have spoken out. Sam has also posted specifically about Thiel (http://blog.samaltman.com/the-2016-election). They've donated to campaigns. They've likely done other things as well. If this one issue is this important to you, indeed, actions do speak louder than words, and I'd expect you to take similar actions in your own lives.
