Katy Perry's Suspect Bipolar Reference

Just when I thought I had zero tolerance for Katy Perry I found it was possible to dislike her on whole new levels. I noticed that in addition to her homophobic lyrics, she's not exactly helping promote tolerance towards mental health problems.

To me, her song "Hot 'N' Cold" says "You're like someone with bipolar disorder and I hate that about you."

She rants about how much she hates a lover being indecisive and then compares his behavior to someone with bipolar disorder:

"Someone call the doctor
Got a case of love bipolar
Stuck on a roller coaster
And I can't get off this ride..." 

Granted, it's used as a metaphor for the ups and down of being in love but perhaps I'd find it less annoying if it was sung in a less angry voice and did not follow remarks like:

"Yeah you, PMS
Like a bitch."

Also unimaginative, trivial lyrics such as:
"We fight we break up,
We kiss we make up." 

don't exactly inspire me to believe that she understands the depth of the problem that she's happy to chuck into her music for the want of a better rhyme for "roller coaster."

Now all she needs to do is insult The Cornish as she'll complete the set.
