So, we've got Kraft, Kellogg's, General Mills, Coke, PepsiCo, and I assume Nestle and Unilever. So basically, for these people to boycott "gay-friendly" companies, they're stuck eating generic brands. Nothing wrong with generic brands, as a poor college student, I'll still use them sometimes, I'd just rather drink Coke compared to Sam's Choice(although Black Cherry is awesome).
Good luck with your little boycott idiots, you'll probably go against it at your next meal.
