It was when I taught his former classes that I was told about how wonderful the UK was, especially the boomtown of Liverpool, by a couple of the students! Of course, I put them right in this regard!

This scouser guy sounds a right loon!!!!

Some parts of the UK are ok,my hometown is not as I hear.

Yep, he was a right loon, according to his actions. I will confirm that.

He had told his students that the UK was wonderful, especially the boomtown of Liverpool!

Ok does not mean wonderful, as you well know. I have no doubt whatsoever that some parts of the UK are ok. However, it's important to call a spade a spade, as you yourself have said. So, let's not fudge the issue! Our readers are not so easily fooled as the general public! Nor me!
