Where? Over a 22 year journey this man has persisted, shown patience against incessant mocking and derogatery comments. After lifetime of trial, trials and tribulations he got to parliament and then reacted to his tormentors. And you want to damn the man. he is not a saint. He is man.
In any interview or speach he comes across as articulate, confident, charismatic politician that puts to shade any other politician in Pakistan today.
And compared to the darn outright insult by India "reveal the true [evil] face of Imran Khan" I think his response on the tweet was measured and proportionate one.
