Imagine the mainstream to be whatever a reasonably informed person that don’t think anarchism could work thinks.
I ask this casually, I don’t expect you to back all claims with citations or anything. I’m interested in learning what you think. I don’t have the knowledge for it to turn into a debate.
I guess you hear a lot of the same arguments/questions, do you have a FAQ or something? (sometimes I think there should exist some wiki with FAQs about all political views, these discussions tend to cycle into the same)

At least for anarchism there does exist a comprehensive faq.
