You obviously have no idea how offensive this is to people with a more conservative political orientation. The left is dictating too much in this so called "democratic" society.
Obsidian's customers aren't all American, buddy; sexual orientation and gender identity and expression are protected characteristics where I live.
I'm not Murican either. I come from one of the most liberal states in EU. People don't like gays for that one reason, they just can't stop getting in your face. Also, they are heavily aligned with the far left including communist sympathizers.
Here's the thing buddy. People will always find something political to harp about. That's their right of freedom of expression (in many states at least). That doesn't mean Obsidian have an obligation to listen. Removing the joke just empowers these crazed militant groups.
Also, have you thought about the correlation between these vile "advocates" and how they have absolutely no qualms about ridiculing the Lord Jesus Christ? Hypocrisy at the finest.
