I hate Daily Mail, it should be regarded as the world's worst newspaper. I do feel bad for Katy none of it was her fault
I've just had a look around DailyStool, doing a search for the keyword 'Katy Perry', and from what I see I can't come to the conclusion that they're normally not hostile towards her, quite the contrary. But the level of intelligence provided by the paper is so low that one may as well not bother commenting either on the articles or the comments as sub comments.
If DailyStool represented the population of the UK in any way I would be ashamed to live there, as well as glad I never applied for a passport. Gladly, I trust that most people, like in any other place of the world, have reached a mental age beyond five years of age though.
