hmmmm

all of these seem to be ways to make the SC work on pages by making the links unusable to the target population.


MY QUESTION:   Why are we adding this SC?

IS THE ANSWER?:   ??Because this group of users cannot use clickable elements that are smaller than  44 px???  (or 100 px by Davids last comment)


SO WHERE IS THE LOGIC — of having an SC that only requires SOME of the items on the page to be large enough for the user to operate but not the rest of the items (including all links) on the page. 
and on top of that, we keep excluding more and more things each time they look unreasonable — further reducing the amount of the page that these people can use. 


If feels like TOKENISM.  ( e.g.   "well, it is better to do something for this group even if it doesn’t really give them access to the page” )


I started my career working with people with physical disabilities like CP — and have a number of friends with CP.   And in WCAG I was looking for both Cognitive and Physical SC to add.   
 But giving people access to part of the page but not the rest — seems like it is of little use. 



ALSO why doesn’t just enlarging the page - and thus making the targets larger - solve the problem?    There is already an SC to enlarge the page - which would do this also? 
someone posted that in mobile you can’t enlarge the page with word wrap — but if that is true — how do we solve the other SC?    (also in mobile — is 44 px any where near as large as it is on a full size screen?   
and if not — then how do they use it if they need 44 px?


confused and feeling we are just trying to do something — without really doing something that is meaningful.  That is a token without real value.  But it makes page design harder. 


This is the end of my discussion of this topic until next draft release.   I find I am repeating myself and that is not useful.

So they may be a fair representation of the site owners that are ether required by law to meet WCAG (or derivatives of WCAG).

So small screen touch devices go into a mode that adds horizontal scrolling when enlarged.  So you are suggesting that it’s ok for users to have to initiate a pinch zoom, then scroll the screen and then tap the target in order to get a target that is large enough for them.  I don’t think this is very practical.
