No one in this world can accept everything, its just some people can tolerate somethings more than others which makes them "open minded" but eventually even they can't take it anymore and decides to do stupid stuff like that!
So no, no one can ever be truely open minded regardless of what they claim... For example I don't have an issue with gays as long as they don't poke around (if you know what I mean) and I love lesbians as well as many other things but I cannot tolerate furries so even though I have an "open mind" when it comes to many forms of sex/love, furries is something that scares me, so yea... (Also, I don't mean that in an offensive way)
