Q1: I'd like to suggest a change. Where should I start?
A1: Great! The first thing you should do is check that no one else has already brought up your suggestion. You can check this by going through the current discussions below, or by searching the talk archives.
Q2: Why does the article describe the Proud Boys as "far-right", "neo-fascist" or as having connections to white supremacists?
A2: Wikipedia is built off reliable sources, and the significant and clear majority of sources use such descriptions. You can see a few selected sources for these determinations in the article's content, though many other sources have also been included in previous talk discussions: far-right discussion, neo-fascist discussion, white supremacy discussion. Discussion amongst editors around this happened in 2020, resulting in an editorial consensus to keep this three terms per all available evidence.
Q3: I have a connection to the Proud Boys, but there's something wrong.
A3: Neutrality is important to Wikipedia, so editors with conflicts of interests are generally discouraged from editing directly, and instead should request edits to be made to ensure their independence. This can be done by creating a new talk section, describing your request (including what needs changing and sources), and adding {{Request edit}} to the top of the section. If there is something wrong like spelling or grammar, feel free to change it yourself, but any meaningful changes are best to be discussed first.
Q4: What sort of policies should I be aware of before I start editing?
A4: If you're wanting to jump in and start editing, it's best that you're familiar with Wikipedia's neutrality, verifiability (referencing), and biography policies. We're all here to help build a better encyclopedia, so if you would like some help making sure your change is okay or would like a second pair of eyes to skim over it before you save it, just post a new message on the talk page!
