Stigmas in our Community

To my knowledge, the Kink Community is the most diverse and accepting communities out there. We have people from all types of backgrounds and cultures, people with all types of kinky desires and needs.
Yet it seems we just simply cannot coexist without some sort of hierarchy of acceptable kink genres. Why is that?
Why is it that some who consider themselves 'spankos' believe that if you use a flogger you are doing BDSM and therefore are not a spanko? Why is it that some Sissy Maids do not accept DL's? That true Dom(me)s cannot every bottom, that true submissives cannot top ... The list goes on.
In the land of MKINYK/YKINMK can we not just accept that while we do not need to embrace anyones kinky nature, we very well can be accepting and understanding.
I love this community. It excites me that I can come here ('here' being any kink community, online or r/l) and gather information, ask questions, find mentors, share knowledge, meet others, find events and generally feel accepted.
I am aware, however, that I cannot share all my kinky adventures. I have to be careful who I share what with, as some of what I enjoy is stigmatized.
I try very hard to be accepting and even when your kink freaks me the hell out, I try to learn a bit about it, in order to be supportive. If you do blood play, for example, I won't watch, but I will help you find the safety supplies you need and be there to listen and encourage you to grow and learn and experience.
I think some people in our community have forgotten (or perhaps never knew) the pain of having to hide such a huge part of themselves away from the world. I believe we all need to check ourselves-are we as accepting as we could be of other people in this community? What group do we look down on? Then we need to learn about that group, to lessen our fear of what they do and be able to say, no, YKINMK but you are welcome here.
Not saying to accept anything that really truly goes against your moral fiber. Some things are just wrong. But if the activity involves consenting adults who are taking steps to ensure that what they do is done as safe as possible, then quit judging
