If you don't like something the US government is doing, you generally aren't going to leave. You are either going to ignore it, or try to change it. Even if your employer is the Federal government, few people would expect you to quit. If your problem is with the exact portion of the government where you are working, then some might expect you to quit but few would bat an eye if your next job happened to also be with the federal government.
What is happening here is akin to being forced out of government work for critizing the government; and we do not accept that behaviour.
