Cherrybim –
“Show me one person who became frum as a result of a kiruv organization/project who would not have done it without the organization’s involvement. That person does not exist.”
Of course, it is impossible to know with certainty that a specific individual would never have become frum had they never had contact with a particular organization.
That said, there are many people whose original contact with Judaism was through a Kiruv organization, and who credit the organization with starting them back on the path to being Frum. Many of these completed the journey with those same organizations.
Your assertion that no such individual exists is flat out wrong, and is a dangerous attack on the neshamos of thousands of as-yet not frum Jews.
