Hi, Newt :-)
There are some in our community, as an example, who believe in feminism (the world's largest terrorist movement). They even seem to think that feminism is the best thing for Girl Love, and that saying anything against it can hurt "our cause". They have to be 100% feminist, nothing more, nothing less. They will not even take up other causes, however honorable, just because they are not in-line with what feminism teaches. They refuse to think outside the box, as part of a guise.
That's just one example, but there are others around who subscribe to all other sorts of ideologies for the same reasons. Different blokes, different strokes, different reasons. We all think differently, but I just don't see the point in being this hardcore stuck to any given ideology. For the reasons I said.
I do not believe there's any collective construct of different ideas put into one ideology that can be 100% correct, or even close. So I will cherry-pick those to my liking. And create my own ideals, as well. No one ideology is infallible.
