Grayzone is definitely very iffy but these specific posts are good. I verified each of the blog posts as well. The issue isn’t “trust”, if I cited a blog as saying something and they didn’t prove their point then it would be a bad citation. The only time I cited blog posts was for analysis of establishment news, and critique them if you like but don’t just go “they’re not valid news sources”, because that isn’t the issue and nothing is claimed as a revelation or without proof. If the issue is with sharing this to other people, then you should first establish what the difference is between news and analysis.
Note: That AP article is far too entrenched in propaganda to be shared as a source. You’d have much more trouble with optics in that case.
I agree that it would obviously be preferable to use prestigious sources with good web design and well-known authors. Unfortunately my resources are limited. Feel free to suggest another article and I’ll consider adding it (perhaps I could make a “mainstream news” section?).
