Then I'd say you either don't know how tragic the situation in Uganda is, or you have no sense of proportion.
"The "not as bad as" argument, or the fallacy of relative privation, is a form of the moral equivalence fallacy that takes note of the existence of things that are worse than what is actually under discussion - for different purposes, as outlined below. It's popular with people who know perfectly well they're doing something wrong; being fully aware that they're doing something wrong, they feel compelled to attempt to justify it and do so by pointing to other, usually worse, actions."
I said the situation in Uganda can't be considered "close" by any stretch of imagination to the situation in California until recently, before gay marriage was legalized. I also implied reaction should be proportionate to the degree of wrong. How the heck did you infer "opposing gay marriage is positive" from that?
You're a random person on the internet, I personally wouldn't rely on any implication to be clearly communicated. When in doubt, be explicit. This is even more important in threads (like these) where people run around with their heads on fire.
No one is making the argument that you are objecting to or using a worse situation to justify anything.
Not just flippantly saying "They can't get married, but they're still alive, right?"
Maybe thinking that it's ALL tragic is the best point of view in moving this world forward.
