if you got kicked out just because of that, then its not worth joining or being a part of...street photography basically means photos taken outside of a studio with subjects in their natural environment, not curated or staged. subjects can be anything living or otherwise, like an empty street (no pun intended)...whatever that captures your curiosity and interest, that you want to capture to convey a feeling...even stuff like still life, random objects found on the street, in a cafe...etc...when you are outside the studio, everything is game, living or otherwise...
