I think you meant "The fact isn't helped with 'almost no' sardars being players or making gfs, etc..."
So to comment on what I think you meant. Singhnis are made to think that they should not get into a relationship because it's either anti-gurmat or anti-culture. Sardars know that ,so they don't bother. BUT others don't and sometimes the Singhni falls for the other guy (or a girl) who took that chance.
That is my theory anyway.
