"Well, I want to sue the homosexuals for completely grossing me out!"
Yeah, I mean, ohmigawd, it's so, like, totally gross!
"Being subjected to their gay pride parades, men kissing men before exchanging nuptials, when they're broadcast on national news stations causes me mental pain and suffering, and I end up with nauseating images in my mind that can't be erased."
Until you change the channel, presumably. Oh no, sorry, I forgot, you're writhing in SO much "mental pain" that you can't reach the remote.
"I want to sue any and all organizations that support homosexuality, as well as the individual homosexuals themselves!"
I want an endless supply of chocolate-coated biscuits served on a velvet plate by singing, dancing pygmies. That isn't going to happen either.
Feel free to launch such a case, but I hope for your sake that you're very rich, not just to fund the obscenely large legal fees required, but also to pay out the massive counter-claims that every homosexual will then quite rightly demand when they collectively lay the legal smackdown on you.
