It was the largest Donald Trump fan site in the world (/r/thedonald before it was shut down for being so big its brigading tactics were damaging the site) and now /r/conservative takes that role. Before it was the biggest Ron Paul fan site. Its deeply pro-guns in nearly every comment section and any mention of Hillary or AOC is an invitation for angry comments and downvotes. Random subs are full of transphobic content and misogyny is near everywhere. /r/conspiracy is a right-wing paradise catering to right wing views.
You cannot talk about money or finance without being yelled at about how bad fiat and the fed are, which are right-wing talking points. You can't have a covid discussion without an army of covid skeptics yelling at everyone. You can't discuss police brutality without dishonest "but both sides" types full of racist dog whistles.
Its absolutely right leaning and token "liberal" positions like legal pot or better healthcare doesn't really change that. I know GOP voters with those positions but they always vote GOP for culture-war related reasons. Not to mention, being able to do drugs in your home is really neither liberal or conservative, its just in the USA only the liberal party is making any effort to make that happen.
Covid skepticism, which spez defends, is extremely coded right-wing, so even leadership acknowledges who reddit users really are.
The few liberal and feminist spaces that exist on reddit have draconian mod rules because of the constant brigading and some of them just give up and lock discussions because mods are exhausted and tired of fighting it. Just running a liberal or feminist or queer sub is a lot of work because reddit conservatives are constantly bridaging. This is not the sign of a liberal community. I mod a few subs and its just a nightmare out there. Just keeping conservatives from trolling and fighting with everyone is a big job. If you see "liberalism" its because the mods are keeping the everyday redditors away and trying to keep up the values and themes of that specific sub and its relatively tiny audience compared to the conservative majority.
Cherry picking AI spammed Bernie posts doesn't change the culture in the comments or what visitors receive when they post. I'm in a lot of Democratic, liberal, feminist, queer, socialist, etc spaces and I can guarantee you reddit is absolutely nothing like those spaces.
Also you are taking my comment out of context, not only is reddit conservative, but as a hypothetic competitor to google its extremely conservative. I can google for things without being hit with Ron/Rand Paul narratives, Trump worship, pro-gun narratives, covid skepticism, transphobia, or racist dog whistles. So just the idea that Reddit is as welcoming as a Google search is very, very questionable. Google will transparently present you ads. Reddit will drown you in propaganda, culture war politics, and harassment. As the meme says, we are not the same.
