Since this is a global change, we should make sure that this checkbox becomes activated in all bars on the site by changing this line to:
```$('.social_share_privacy_area label[for=' + click + ']' label[for=' + click + ']').addClass('checked');```
and adding this 
```$('.social_share_privacy_area label[for=' + click + ']' [id="' + click + '"]').prop('checked', true);```

(In the 'else' part we need the equivalent lines as well)

Does this make sense? Would you like to add it to your pull request?
