I guess I understand what you're saying, but it's just a matter of what you care about.
Very true.
Everyone has different priorities.
I like to be in proportion, but I admit I like to have big arms. Have you ever heard someone say "wow did you see that guy's glutes? He's huge"
Again, different priorities for different people.
Some people who have trained hard to get in shape - and as a consequence - develop impressive physiques, and enjoy showing them off in public. And these people might even dress in a manner that draws attention to their physiques - i.e arms.
Some others, on the other hand, with similar amazing physiques, couldn't care less if people notice or not.
