Physics is a science has professional standards as per what is worthy of teaching others. Your philosophy does not scientific standards, so your argument is a false equivalence.<quoted text>
My position is coming from a position of Truth. If I discovery a new atomic particle I would want to share this knowledge with everyone, whether they believe it or not. They may say I didn't find a new particle or they can perform the same experiment I performed to see if the particle truly exists. I found God and I will share the knowledge of Him to everyone, and they can say I am wrong or they can also seek God to see if I am right. As I said before there are many spiritual disciplines that may aid one in finding God.
The point remains, you are not preaching because you WANT to, you are preaching because you NEED to, in order to construct your indentity (i.e. be who you are). That is an absurd way to go though life, in my opinion, and certainly very codependendent.
