You really find Chick-fil-a appetizing and support gay rights at the same time? I'm jealous of you - I once loved it, and now the idea of eating there makes me slightly ill.
It's your own personal decision about what you want to support in this world, but everybody gets to have an opinion about it esp. if you announce it on the internet.
Inertia because inertia is not an argument, it's just what inertia is. When you shop at companies that do things that are morally reprehensible to you, while avoiding a million other options, that just sounds like apathy.
