One should bear in mind the difference between "Intentionally" and "Unintentionally". The purpose of one's remarks and the way he/she make these remarks is also considered. I am not advocating the blasphemy law, you are right that it is being misused specially in minorities cases but it can be seen clearly that purpose of JJ in his statement was not what it is being taken and now some so called mullas who themselves have made such type of statements have got an opportunity to create ill feelings against tablighi jamat.
