In my opinion, i think you have to make a decision of what is more fearful to you: either you going to a foreign country and maybe you get threats or even get hurt. OR are you more afraid of the direction of the Brazillian government.
From what you wrote, it sounds to me like you are genuinely concerned about the topic on which you are going to write. Therefore, the people reading your work will gain courage, knowledge, and possibly the same conviction as you to make a difference for humanity over in Brazil, which many readers may not even be aware of.
Good luck!
