Answer:
Whenever someone sees injustice happening around them , they should stand up.
It's not only about the teenagers , it is the duty of every human being who has even a glimmer of humanity in them to stand up for those in need , to stand up for help, to stand for injustice.
The fact that whether teenagers should stand up for injustice in the absence of a support is the question risen here.
Well I think they should.
Most people get scared to do so, mostly not because they are coward , but rather for the fact that " Why should I stand up for it when it doesn't bother others" .
It is one of the most inhumane thing one could tell to themselves.
I suggest them to stand up for justice but by not being aggressive but through nonviolence.
