Different Drochim in Judaism

I have a friend who tenaciously defends different drachim in Yiddishkeit, although they greater differ from the derech that he has chosen. I asked him about why he so passionately defends those drochim. He answered me the following:

"I have thought about why I feel so passionately about defending different drachim of Judaism. I think (and I hope that I am being honest with myself) that there are two primary reasons. Firstly, I think that it’s important that all drachim that lead to Hashem, even if do so imperfectly, as long as they lead in the right direction, should exist in the world. There are many ways how Hashem is revealed in the world. Secondly, lemaaseh, these drachim should be available to people who would gain from them. If a certain person needs a certain derech, and other drochim don’t work for him, how can we not be pained that the derech that would lead him to Hashem is not available to him!?!
I understand that these statements need to be refined before they can be used for hadracha maasit, and certainly not every derech is legitimate. Nevertheless, I strongly believe that what I wrote is the truth."
