What's totally needed is more meme-crap posts that fill up space, shitposting, ad-hominems, racist crap and now the latest fad, glorification of illegal stuff etc. Let's break the law right here on NMA, I'm sure Gonzalez will turn a blind eye. What ever will happen next? Stay tuned, same bat-time, same bat-channel.
I have no idea what sort of meme-crap and shitposting you're referring to. I have seen little of it. Besides, even if I did, it's a forum, that's a normal thing to occur to a certain extent. Beyond it, it is removed. Check The Vats and tell me mods aren't clearing out spam and shitposts.
The rest of the stuff you mention isn't wrong either, according to forum rules. I don't condone racism, but it's bound to happen on every forum with this many people of various beliefs and opinions. Users have the right to be assholes as long as it isn't against the rules. Free speech and all that shit.
Nobody gives a flying fuck about drugs or whatever being discussed. Discussion is never illegal, even in real life (few fucked up countries aside). Nobody is selling shit here, nobody is distributing child porn, or even some "innocent" stuff like pirated material, so your statement makes zero sense. I can say right here and right now that all children should be given heroin at birth and I have 100% right to say it. I don't believe in it, I don't promote it actively (or for real), but I can say it (if just to troll people). Same goes even if I believed in it. It's not against the rules. Nor is it against the actual law in most of the countries, which you mention for whatever reason.
If that's too much for you to handle, then sorry, the issue is with you, not with the rest of the forum.
Sander was wrong because he often banned people because they didn't fit his worldview or agree with him, and not because they broke the rules. And rules exist to be neutral and impartial, and administrators should be enforcers of those rules. If they cannot do that job properly, they are not fit for it, and in my opinion (and of many other people here), Sander crossed that line many times.
He's not active anymore, so it doesn't matter much, but I don't want to see him come back. As a regular poster, sure, as an admin, no.
tl;dr None of the things you said are true or against the rules (which you should read if you haven't). Whatever issue you have are yours only. If you can't understand that, sorry. Nobody cares.
