When I wrote the post on #StandWithJNU yesterday, I was not aware of a petition that students in IISc and NCBS (and, probably, several other institutions) have helped in drafting [I thank Vishu Guttal for the pointer]. The petition is admirably clear, direct and forthright in stating, "By stifling their [Rohith's, Kanhaiya's and other such students'] voices, the government crushes not only the voice of students as a community but of marginalised students in particular. Against this we must collectively stand, and declare our resistance."
Also worth noting: the petition is available in many Indian languages.
Read the petition, and sign it if it speaks to you. [I have signed it, and I see several familiar names in the list of signatories.] Also, please do share it with others you know.
