Deism is the logical conclusion from Kalam. Which is what he is arguing.
Sort of.

I know - I was going to make reference to "his (Sanmario's) cosmological argument" but decided that he probably would not know that's what it was.
Earlier he also claimed that Nature is the same as God - and then got upset when I suggested he was a
pantheist.
Then he argues that observation and reason lead to the intelligent conclusion of an impersonal God. This, very definitely, is the
deist position in a nutshell.
Yet, having made very clear statements of two alternative non-theistic positions, he expressly avows
theism.
As you say, deism is the strongest possible conclusion of the cosmological argument - although even that depends on a prodigious philosophical leap of faith. Once could just as easily conclude that the universe had an unintelligent and naturally beginning-less cause (which, if you want to deify this, it would probably be closest to naturalistic pantheism - a kind of Spinozism -
Deus sive Natura) of its existence rather than a supremely intelligent and supernaturally eternal cause. There is logically no difference between the two as far as the cosmological argument is concerned.
There is
no way to get from a cosmological argument to theism by logic.
But it's even worse than that because, unfortunately for Sanmario, all cosmological arguments fail logically because their conclusion is that the beginning (for example, but if we want to use Aquinas' version the motion...etc.) of all things is itself beginning-less (unmoveable...etc.) and therefore refutes the premise that all things have a beginning (are in motion...etc). Moreover, in this case (Kalam), the argument hinges on the assumption that the universe itself had a beginning (began to exist) - and there is manifestly no possibility of proving this - one way or the other. When both the evidence and the conclusion refute the premises, it isn't clear that you even have an argument, much less a convincing one.
And, yes, I know he (Sanmario) ain't gonna be swayed or appreciate any of this. But there it is anyway.
