It's interesting how the so called hyper progressive spaces are simply the LGBTQ communities. As usual this sounds like a clear elevation of antiqueer views and people over the lived experiences of a community that has an intrinsic right to exist.
Edit: A reminder to everyone reading this, claims of being neither left nor right are nearly always made by the right. Particularly when the left in this instance simply means people who are queer.
What are some examples of dogmatism and extremism from the progressive side that you hope to avoid?
Like spaduf says, those "both sides" claims often come from the anti-queer folks, and while I want to give you the benefit of the doubt, it's difficult to tell what sort of community you're trying to cultivate.
You can't both sides the existence of a community of people. Anything that doesn't explicitly reference the long history of academic gender and queer theory is trying to do just that.
