When humans have done more harm to me and those I care about than any other species of person, I would be a fool to write off all risks. Yes, do not live in fear and let it control you. Do not live in fear and let it breed unnecessary conflict between you and other persons. That is very rarely a good thing for one's mental health or for interpersonal relations. But do not write off that caution (and sometimes fear) is warranted. That's my take.
