If you get teased for liking the rainbow, it's because OTHER PEOPLE are homophobic. That's not the fault of homosexuals.

Also, the line in the secret, 'You're more GAY than I ever will be', reads as something rather homophobic.

"Why should I get teased just for liking the rainbow? Surely, slashing your own sex would be better grounds?"

What are you trying to say here? Slashing your own sex would be better grounds for being teased, or better grounds for liking the rainbow? Neither makes much sense.

Bottom line: even if you aren't, at heart, homophobic, you're looking like one. SHAPE THE FUCK UP.
