I am born in a Brahmana family and I had my threading ceremony. I did receive this knowledge in the Guru-parampara system and I can defintely talk about it. I went to ISKCON to learn about Baghadvad Gita and the Vedas and learned it from a authentic Spiritual Master Srila Prabhupada.
So I carry a certain bit of authenticity with me. What ever I say is the knowledge passed on me for generations.
