I guess that makes this more of a meta-question, not a direct question. How can I learn about more open communities that may exist on the net where I can have the type of discussion with people that was possible 15-20 years ago?
Topics of interest: hacking (actual, not just in the name), startups, entrepreneurship, internet marketing.
I'm curious why you feel being able to use offensive language and express "opposing views" (whatever that means, I assume politics) is particularly germaine to high quality discussion of those topics.
If all you're looking for is a place where you can be an edgelord without consequence then there's always /g/ and 8chan (on the dark web as 8kun,) and maybe Voat and Gab.
If you're itching to call someone the N or F word or want to brood about the sudden rise of feminism in America, may I suggest finding a pen pal and communicating that way?
