You miss the point, it is not simply that this App is "offensive" and it is not that those who object to this App are simply trying to "suppress the views of others", they are objecting to the fact that it spreads malicious falsehoods about gay people with the implication that being homosexual is an "illness" that can be "cured" by techniques that are dangerously close to brainwashing.
This App goes way beyond expressing a viewpoint and into highly dangerous and irresponsible lies which may well have resulted in the suicides of some of its victims.
