Living your own life, you become accustomed to doing things certain ways; daily rituals and traditions. For an example, making a sandwich, I like to build my way up. I enjoy when its the bun, meat, cheese, vegetables, sauce, top bun. But, is that the right way? Technically, there is no right way to do anything, but to build a sandwich, my way is politically correct. You may think that the way you do something, is the best, and most perfect way of accomplishing a task, but there are millions of other ways you can do so. Once you become so accustomed to the idea of your right way, you begin to believe others are doing it wrong. For example, I became so accustomed to my ritual of: bun, meat, cheese, vegetable, sauce, bun, that if it is built in a different order, I like to rebuild my sandwich to fulfill the way I like it. Only because, that is my right way. I do understand, that other like their sandwiches built differently, some might not even care.
What about beliefs? Do you believe that your religion is the only right religion? Do you belief that everyone else is wrong, and that they will not make it to Heaven, because their practice is different from yours? If they do not worship Jesus Christ they will not make it to Heaven, because they worship other gods? There is no right way. Whatever that person believes in, they will get there.
How about sexuality? Do you believe that because you are heterosexual, every other sexuality is wrong? It’s not wrong, because there is no right way. Love is love, and how somebody else loves, does not effect you personally. No matter the sexuality, straight, gay, bisexual, asexual, pansexual, etc, its their way of love, and there is no “right” version of love, because love is love, and you cannot stop love.
The traditions, rituals, and ways of life are completely different of others, but because of the differences between yours and their life, that does not mean they are wrong. Everyone has their own “right” way, and you just gotta let people live their own lives, in their own “right” way. Theoretically, the right way does not exist. You just have to get through life the way you need to do so, and that way is the right way.
