Alright I'm not going to chime in on the picture or the outrage to it... but the fact that you have "NEVER been offended by anything to do with [your] race, ethnicity, religion, gender" is kind of an informative statement when it comes from what I assume is a white Christian male. If I am wrong feel free to correct me. But saying "I've never been offended" when you are a white Christian man in America is pretty ignorant of what other people go through sometimes. And this post is coming from a white Christian man by the way
With that said there are real issues out there other than a Three Amigos photoshop that would be a better use of everyone's mental energy so maybe the people who are offended by the photo should re-prioritize
So...you're offended that he's not offended?
