Do you find it equally difficult to take seriously those who engage in "Buddhist practice" but still identify as Buddhists?
No. I answered that in my previous post. Taking refuge and having faith in Three Jewels is an integral factor of awakening in Buddhism, to liberation in fact.
I came to the Dhamma as a non-religious person and have remained a non-religious person, why would practicing the 8-fold path change your religious outlook?
As did I.
The Noble Eightfold's entire purpose is to change one's religious outlook- it's a religious teaching. It presents an answer to the suffering of this life and future lives. That's a religious question. Buddhism teaches metaphysical answers to resolve the conflicts of the human condition.
Additionally, the Buddha first taught the Noble Eightfold Path to five ascetics searching for liberation with one instantly attaining liberation from re-birth. At the end they become his students and the Gods in the heavens celebrate the teaching of the Dhamma. How is that not a religious text? How can the Eight Fold Path come from a religious text, tradition yet be non-religious? That's truly cognitive dissonance.

Buddhist, a Christian, a Muslim, etc... will gain a deeper understanding of their religion as they practice sila, Samadhi and panna.
I would say that a Buddhist gains deeper insight into the teachings of their own tradition. I'm not of the mind to state that the experiences of my religious tradition are equalivant to the experiences of other religions. Personally, I find that to be rather shallow. How can I say what a Jew feels when they read the Torah or when a Hindu visits the Ganges. It's not a one size fits all for religious experiences. I don't buy into perennial philosophy, which is what you maintain here.
I would not say the practice is Buddhist, which Buddhist practice would you be referring to?
Avihiṃsā is a good example. Certain traditions sacrifice animals for religious reasons, including Islam (to use one you just mentioned above). Buddhism condemns animal sacrifice and states that it is not a valid method to gain awakening. So I would not say that a religion which teaches animal sacrifice leads to liberation; this is absoluetely contrary to the principles of the Supreme Buddha's teachings.Practicing avihiṃsā comes naturally as a result from following sila, metta and so forth. It's a transformation of the mind.
At a depth of understanding you may find many similarities in the suttas, and the bible.
The bible has some nice words of wisdom in some books. It is also full of horrorific episodes of genocide and slaughter. I fail to see how the Suttas and Deuteronomy 13 can be reconciled.
Are you suggesting the 8-fold path is not a spiritual path?
Nope. It's a religious path. "Spiritual" is very vague these days.
What deeper truths?
The ones taught by the Buddha himself. You are going to die. Everyone you love is going to die. Everything you work for will fade away. How do we handle this? How do we live with these truths? How do we die? The Buddha teaches that we are inheriting this from a pervious life and it will follow us to another life. Personally, I find the struggle with this to be what the Buddha said- it is Noble. It's also very difficult to resolve. It's far more Noble than learning of ethereal concepts of emptiness and clear mind states etc...
"There are these five facts that one should reflect on often, whether one is a woman or a man, lay or ordained. Which five?
"'I am subject to aging, have not gone beyond aging.' This is the first fact that one should reflect on often, whether one is a woman or a man, lay or ordained.
"'I am subject to illness, have not gone beyond illness.' ...
"'I am subject to death, have not gone beyond death.' ...
"'I will grow different, separate from all that is dear and appealing to me.' ...
"'I am the owner of my actions,[1] heir to my actions, born of my actions, related through my actions, and have my actions as my arbitrator. Whatever I do, for good or for evil, to that will I fall heir.' ...

I am taught that no conversion from one organised religion to another is necessary, to practice the 8-fold noble path.
Ok. I've been taught the opposite.
You mention that it is up to every individual to decide if they feel ready to convert and then in another breath you claim this is automatic as one begins down this path???
Nowhere did I say that conversion is automatic. It appears you misread my post.
Lastly, this post has strayed far from OP's topic. I'll let the mods decide if they want to make a new thread.
