I agree with you 100% in principle. The issue that makes things different now than say 20 - 30 years ago is the extreme positions that certain politicians hold. My wife is an immigrant from the third world and there are lots of politicians (and their supporters) who genuinely believe she should not be in America.

How should I feel about this when I see a sign that supports these views? If I stop patroning the business or actively organize a boycott, am I continuing the cycle of hatred? If I ignore the political beliefs and continue to support the business am I betraying other people who are similar to my wife? Simple things that we all used to take for granted, like supporting businesses whose owners have different political perspectives, are not so simple anymore.
