The OP doesn't really present this as a discussion of whether evangelism is good or bad, but more about when deceit or misrepresentation is used.
I admit I do not particularly like evangelism. I find it presumptuous, and insulting.
However, there are some evangelistic efforts that are much more irritating and unethical than the average effort. What is the value of a conversion if it is based on lies and deceit?
Does the ends justify the means??
It reminds me of what Paul said in 1 Corinthians 9:
9:20-22
To the Jews I became as a Jew, so that I might win Jews; to those who are under the Law, as under the Law though not being myself under the Law, so that I might win those who are under the Law; to those who are without law, as without law, though not being without the law of God but under the law of Christ, so that I might win those who are without law. To the weak I became weak, that I might win the weak; I have become all things to all men, so that I may by all means save some.
So it seems to be one of Paul's tactics. I don't see that type of tactic associated with Jesus though.
Even though deception was used when approaching the person, there has to be some point at which the person knows he/she is being spoken to concerning Christianity. At the time they convert, they know what choice they are making. We aren't talking about the Spanish Inquisition where the choice is convert or die.
I would think the validity would be determined by whether the conversion sticks or not.

That's where it is the parents job to watch over who their children interact with so they aren't deceived or manipulated.
