That depends on what the words "science" and "evolution" mean and on what differentiates science from other sorts of belief systems.
That's just it...science isn't simply a belief system. It is based on the scientific methodology, and the weight of observational and experimental evidence.
I'd say that 'biological evolution by natural selection' is an explanatory hypothesis. It's certainly consistent with a huge body of biological observation. It provides us with a story, a narrative, that seems to explain what we see. But it isn't as good as the "laws of physics" in generating testable predictions. So it might not fit all that well into some formulaic "scientific method" model.
I wouldn't say that it's "shameless" at all. But I do think that some of its opponents along with some of its defenders are indeed shameless. That's almost always in rhetorical writing directed at persuading the lay public to believe as they do.
Correct me if I'm wrong, but what I read there is that, yes begrudgingly the evidence is there for biological by natural selection, [darn it!] but I still want to leave the door open for some form of ID.
Then you go on about shameless "defenders"...what shameless defenders? Me for instance? OK accepted. What about Richard Dawkins? Surely you cannot call him a shameless defender, when all he is doing is promoting the fact that Darwinian evolution is part and parcel of evolution as a whole, as factual?
Descent with modification and survival of the fittest seem rather observationally validated from my own inexperienced and non professional position, and yes, you could then accuse me of some faith based belief.
My IQ [many years ago] stands at the higher limit of average, and I see accordingly that "faith based belief ", imo is overwhelmingly supported by the preponderance of evidence and logic.
What convinces you is up to you.
A philosophical question arises there concerning what
should convince people. That isn't really a scientific question in my opinion but more of an ethical one, a place where ethics and epistemology merge.

The majority of people are average, obviously, and many of those have an in built fear of the finality of death, as indicated by science. That fear is strong, and this, along with religious teachings that promote an eternal life after death, helps them maintain that warm, fuzzy inner glow of warmth. That's OK...I do not personally go out to destroy that, unless that individual, decides to mount a white charger with sword in hand and start some silly crusade against science.
When that happens they get what they deserve. I don't force my way into a church and tell the congregation, that they are being led up the garden path by the nose!
As for me, I'm pretty much convinced by 'biological evolution by natural selection'.
I think that biological evolution by natural selection is probably true,
I can't say for certain that it's all that's happening in the history of life, though as a matter of practice I tend to think as if it is. A And biological evolution by natural selection is the best naturalistic account that we have.
And I can't really say that I know that it's true. It's more that I assume that it's true, as my working assumption when I conceptualize biology.
OK, to me anyway, it appears you still have some nagging doubts. sadly I'm not educated in this field enough to convince you one way or the other.
Personally, I was raised as a Catholic and was also an Altar Boy. I have nothing but respect for them generally speaking, and in my time at school and as an Altar Boy, never once, even remotely, was confronted with any type of sexual harassment, and neither were any of my old school friends of which 9 still remain in our regular get togethers for a piss up. That despite the many revelations of school children being abused by religious teachers. Mine were the Christian Brothers.
I also have a Parish Catholic priest still as a personal friend and acquaintance, despite our obvious differences, just as I have many friends of all different colours and persuasions.
We often discuss science together.
