St Stephen’s principal Valson Thampu who has been under constant attack by certain alumni of the college for allegedly bringing bad name to the institution, on Wednesday dared them to debate the “facts” with him on a “neutral forum”. Thampu, also claimed that his tenure has been a “nightmare” and referred the alumni pointing fingers at him as “disgruntled elements” who pretend to have love for their alma mater. “Both sides being heard on an equal footing is the essence of any debate. This bottom-line norm is sought to be perverted by a few disgruntled elements into a stone-pelting exercise, with words for stones,” he said in a Facebook post. “I challenge these misguided Knight Errants of the bash-St Stephen’s chivalry code to debate the facts with me on a neutral forum. Unlike them I am not an expert in stone throwing,” he added.
