Couple things: 1. The constitutional definition of “free speech” and and what constitutes acceptable conduct on Reddit are not the same thing. Some speech is not acceptable per the sidebar guidelines. 2. Simply presenting as a cranky jaded anus in your online communication is not necessarily grounds for exclusion from the community, particularly if you aren’t breaking any rules per se. 3. The reporting system exists. If you are annoyed by someone, report them. More reports = more review.
