Some folks aren't understanding the difference between something being publicly accessible but still not "a public space."
This is a MODERATED forum. Over the years it has established itself to have a certain personality, for lack of a better term; and it is moderated to fit that personality. Yes, it can be exclusionary, but only to people who argue excessively about the personality and try to change it. Otherwise, we want it to be open. When someone is banned, it's not us being cowards, it's reducing excess noise from someone who doesn't respect what this forum is about.
There are a good number of very technically-inclined and experienced people here. They freely give advice to those who ask, some design their own equipment, and overall have earned the respect they get. I have seen countless cases of people posting pictures and getting some great advice about what is good and bad about a design.
As a group, we DO listen to a lot of music. There are dedicated threads for this, but there are also many threads for other things as well; we're quite an eclectic bunch. When it comes to equipment, though, we're not going to ONLY judge based on sound. As I mentioned before, sound is on par with build quality in this forum, and even if something sounds good but has potential build issues, it will get called out. That is part of the personality of this forum.
I will read and respect someone's thought on sound, but will also read and respect good technical input, brash or not. If something is built well and sounds good, it gets praised. Otherwise, it's open season for criticism (based on sound or build). Again....this is the personality of this forum.
Accept it, join and try to have fun. Or leave. But if you keep fighting it, you will be banned - to reduce the noise.
