it depends in part on how you define "danger" and what your definition means to you. In the case of real danger to life... well, with the exception of the most rare of circumstances it is best to hold one's tongue to live to speak another day. But if "danger" to you means criticism, rejection or other forms of psychologically painful events... then you need to weigh those things out and perhaps re-evaluate them.

we are raised to admire truth-speakers of our histories... the one who stands alone for truth, but in reality we generally marginalize and reject those people in that moment of speaking the truth.

speaking one's mind isn't the best activity to make one popular, if that is a goal. Also, speaking one's mind isn't the same as speaking the truth necessarily.

you are speaking in a way that really makes it difficult to ascertain what it is you are actually asking though... so i may be way off base
