NEW DELHI: Congress vice president Rahul Gandhi has said that Modi government is "bullying" an institution like the Jawaharlal Nehru University and it is "completely condemnable", but at the same time asserted that anti-India sentiment is "unquestionably unacceptable"."Modi Govt & ABVP bullying an institution like JNU simply because it won't toe their line is completely condemnable," the congress vice-president said on Twitter. "While Anti-India sentiment is unquestionably unacceptable, the right to dissent & debate is an essential ingredient of democracy", he added.Gandhi's remarks came within hours of the arrest of JNU students' union president Kanhaiya Kumar in a sedition case over a protest event at the campus against hanging of Parliament attack convict Afzal Guru , which sparked massive outrage among students and led to criticism from non-BJP parties which dubbed it as an "Emergency-like" situation.Kumar was arrested on Friday and later remanded to three-day police custody by a local court, a day after police filed a sedition case against him on complaints from BJP MP Maheish Girri and ABVP members Earlier in the day, Union ministers Smriti Irani and Rajnath Singh advocated strong action against those involved in the alleged "anti-India" act even as students continued with their protests on the campus for the third day, saying they are being "witch-hunted".Questioning the filing of sedition case, Congress leader Kapil Sibal asserted that it was a very serious charge and the BJP government should think before taking action under it.Gandhi had played a key role in protests over the suicide of the dalit scholar Rohith Vemula at the Hyderabad University last month, an issue that had led to outrage over campuses of several universities in the country.
