The problem with cheddar is that it's so ubiquitous it's been replaced by yellow blocks of stuff that I'd barely even recognise as cheese. Even in the country of its origin, it's difficult to find cheddar. When you do, though, wow! I promise you it's nothing like what most people think cheddar is.
You are a freak of nature!
Just kidding. My awesome but late grandfather hated all cheeses. I think it is normal, but maybe not so common. You are special. ;)
What an epic question, almost worth typing....
