learn Aikido and--or similarly non-violent self-protective skills (a dojo may exist in or nearby your locale)
learn "NVC" (Non-Violent Communication) to help avoid angering anyone and to peacefully resolve conflicts
we should refrain from involving directly with anyone with (severely) nefarious intent (never insult nor threaten such a person)
"do not resist an evil person"
Matthew 5:39
in other words, we should refrain from fighting against evil if this occurs
if necessitated, we could use "NVC" and Aikido to facilitate acceptance from anger and to redirect evil force to harmlessness
safer still may be to calmly escape a bad situation, ideally in secret and silently
if you desire help to lighten your mood and learn something for safety, I recommend watching the movie "The Karate Kid":
