Rather than forcing the entire world to change to fit your world views and personality, it's always a better idea to simply stop seeking validation from the world and stop caring about things like this. If you are feeling excluded it's because you are choosing to feel excluded, not because anyone is deliberately trying to make you feel that way. I am a western person living in an incredibly exclusionary and xenophobic east Asian country and if I cared about every time I'm treated differently, I'd go nuts. And since I am a white person living among a bunch of Asians, trust me when I say that I get treated differently all the time. People often start acting differently when I enter the room, store clerks and waiters often treat me a bit different than the locals etc. And you know what? Most of that is not even intentional. It's just the way humans are and that's ok.
You can't force people to give up every single piece of their identity and what makes them different in order to fit this new politically-correct bland mold of people who all act and think the same so that no one feels "excluded". As humans we are different, diverse, have different types of humor depending on the geography, age, gender, subcultures etc. Being able to cope with that is part of being a mature, well adjusted person.
All this PC "let's-all-be-the-same-hold-hands-and-sing-kumbaya" crap is getting tiresome. It goes against everything that makes us human, different and unique. If that's the world you want to live in - fine - keep going with your crusade and feeling indignant every time someone shows a trace of uniqueness and being different. I for one refuse to live in such a suffocating colorless world. I love being different from other people because everyone is more interesting that way, and yet at the end of the day I can still find a way to relate to others.
The world owes us nothing. If you decide to take away positive aspects from your daily experiences, that's what you'll get. If you decide to feel miserable and angry when people don't act the way you want them to act, then sadness and misery is what you'll get.
Since I know that some blockhead is going to try to strawman me, I will preempt that by saying that I don't believe we should start calling black people "niggers" or take away women's right to vote. Just saying that if people manifest their diversity in a way that's not harmful to others, there is no reason to get upset.
