Swedes are not sensitive (4-7)
I believe the answer is:
thin-skinned
'sensitive' is the definition.
('thin-skinned' can be similar in meaning to 'sensitive')
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for thin-skinned that I've seen before include "Easily offended" , "Quick to take offence" , "Irritable" .)
