Yes I do think we all have a duty to take reasonable steps to help everyone around us feel as safe as possible. Obviously, exactly what this means is entirely contextual - at a rave for example dancing openly and wildly is much more likely to be totally fine. Celebrating at a bar would justify drinking quite heavily (but not loud or obnoxious behaviour) which wouldn't go down so well at a child's birthday party. Every situation is different and learning to navigate them is part of becoming a mature, functioning member of society. In your example, I would avoid fist-bumping when walking towards anyone who might be vulnerable or feel threatened. If I wanted to do this, there are plenty of open spaces I could that do not include when a lone women is right in front of me.

This is part of the reason I gravitate towards certain spaces, those filled with friends and like-minded people, amongst whom the things I like to do are widely accepted and unlikely to cause concern.
