Hi Gregg

There has been a lot of discussion around the value of SC target size and the exceptions and whether the latter diminish the value of the SC so much that we can jsut as well abandon it.
Let me take you point one by one:

>> "The few targets That qualify HAVE to be larger or people can’t use them, but it’s okay if the vast majority of the targets on the page do not qualify. 

It is not "a few targets" - for example, the site navigation is not exempted and is of critical importance to making content accessible. Navigation links will be a lot mote likely to be selected than inline links in some content. So it is not a matter of 'vast majority' but a qualitative differnece between (permanent, criticasl) navigation varying links in content.

>> It is not important for people to be able to access those. Those can be small and the person can still use them fine (for some reason we don’t state)  OR   people don’t need to access links in text.

Sure, in many cases users will also want a larger target for links that are exempted. A desinger is free to follow AAA to provide that to all links. THe SC as it stands was a hard-won compromise faced with pushback in comments that suggested that requiring the size that user research (and available recommendations for mobile platforms)  would not be acceptable. 

So true, we chisseled away via the lst of exceptiond to end up with something that put the requirement on the map for the first time and would improve usability for important parts of content (but not all). That is a trade-off that I find worth accepting.
>  The logic of this SC  completely escapes me. Either everything needs to be large in order for the person to use it or else nothing needs to be large because the person can use the smaller links in text so they can also use the other targets if they are the same size.

I am sorry but I don't get the 'all-or -nothing' approach. Often no progress is possible when you ask for to much. As you have pointed out, there are ways to zoom into content e.g. if using text links is necessary, so the exceptions are not a showstopper. Still having good target sitze on most important / frequently used interface elements still brings a huge benefit to users.
>  this looks like we are trying to create an SC rather than we are trying to solve a problem

I don't know what you intend to say here.

>  if the person needs to have things better in order to hit them, then they need to have everything bigger or else they won’t be able to access everything.

I think I have covered that in an answer above.
> What am I missing?

I am nor sure. I hope you find my answers clarifying.
