JRichard, I will expand on my objections a little more so we have clarity...
Universal Sanction is not an adequate criterion for properly basicality because:
1) if for instance, there was a belief held in a specific region by 100% of the population and this belief was not universally sanctioned. Then the rest of the worlds population was destroyed - this would render this new belief as universally sanctioned. This is absurd to consider that some beliefs should be properly basic because they 'happen to be'.
2) Sennet does not conclude that rational intuition, introspection, perception and memory beliefs exhaust all of the types of beliefs that can be properly basic.
3) This relates to #1 and #2.... When we talk about whether or not a belief satisfies the pragmatic skepticism condition of universal sanction we actually don't have any idea what this means. When you say 'theism does not satisfy the pragmatic skepticism condition because atheists get along fine with theistic beliefs'... Well, you get along fine according to who? You don't have a relationship with God. Why do you think you get along fine? This criteria is not conclusive and it really depends on 'fine according to who?'. You might be able to survive, but fish survive without memory beliefs. Are you about to say that this is only essential to humans? Once again, an ad-hoc explanation. Further, if you make it based on some cognitive standard, then we certainly don't have any agreement, because a conclusion of Plantinga's model is that atheists are cognitively handicapped.
FYI, these three points should be taken together. Please do not reply to them individually...
Here we see the relativism of universal sanction. Theism can be said to be universally sanctioned because if theism is true, then atheists are cognitively handicapped. In the case of the above counterexample we have a group of individuals that after 'culling' the population end up as the majority. The only thing that stops a segment of the population from declaring their belief as universally sanctioned is majority opinion, which is an arbitrary criteria...
Regarding your objection that Plantinga's defense is trivial... The problem is that atheism cannot be said to be arrived at rationally. This is Plantinga's argument against naturalism. You also brought up the Great Pumpkin objection again. Here was the response I gave to shunydragon:
In reply to your objection that "Plantinga's defense doesn't actually convert de jure objections to de facto objections, since it involves and ad hoc re-definition and strawman of what Christianity is committed to". Plantinga is meant to provide an intellectually defensible model of how Christian belief is warranted if true. This point is worthless, because he was not meaning to imply that knowledge of his model is required for salvation.
I never said that evolution cannot select for true beliefs. In fact, I clearly stated the opposite numerous times... I was saying that evolution does not select for necessarily true beliefs. For instance, the belief that 'my cognitive faculties are reliable'... P.S. I am using necessary in relation to pragmatic indispensability. This may be an interesting side discussion, so if you know how evolution selects for that, then please do tell.
I also did not intend to say Plantingas argument concludes evolution does not produce necessary truths. You are just distracting from the main discussion. Slightly tiring, because it is not a huge deal. The rest of what I said was still valid and on point with Plantinga's argument...
No, you are confused again... I was showing that there is no intellectually defensible account of naturalism. I actually explicitly stated that naturalism can be true, yet the belief in naturalism would not be warranted given Plantinga's criteria.
Now you are just harping on one mistake I made. Plantinga's argument is still cogent...
Right, evolution is a process that is taking place right now. What is the probability your beliefs are true at the current stage in evolution?

False. Your claim makes no sense. Do you really think that all theists need to do is show that it's possible for an evolutionary naturalist to be wrong? Do you think that suffices for a defeater? If so, then I have a defeator for theism right here... it's possible that theism is false.
Yes, it's possible for natural select to select for a false belief, just like it's possible that a deity is deceiving theists into having a whole bunch of false beliefs. The mere possibility of that is not a defeater for theism nor evolutionary naturalism, anymore than the fact that it's possible that the universe began 5 minutes ago serves as a defeator for Big Bang cosmology. Showing that "X is possible" is only a defeator for positions that claim that "X is necessary". And evolutionary naturalism has never been committed to the claim that 1 is a necessary truth. To say otherwise is to strawman evolutionary naturalism.
Evolution is more likely to pick up on the belief, the more rounds of selection that belief goes through. Furthermore, evolution can select for reliable cognition that results in more than true beliefs than false beliefs, even if evolution didn't select for a particular belief that results from such cognition. Thus a particular "less important belief" (as you call it) might be more likely to be true in virtue of being produced by a reliable cognitive system that was selected for by evolution, even if that particular "less important belief" was not itself selected for.
