Indeed, the assertion that this forum has become alt-right is absolutely ridiculous. People need to take a look at the
political compass topic and see for themselves.
@Scopa did a good job aggregating the numbers:
What this forum is witnessing are lots of moderate left leaning people finally speaking out against the far-left militants now that they are allowed to speak. Past forum moderation has been fighting hard to silence those people to make it seem as if their political radicalism is the default left position. Now that a broader spectrum of views and arguments are allowed, the forum has managed to become more politically moderate, which is a good thing.
Yes, we also have gained a few right leaning people. There is absolutely nothing wrong with that and as long as they don't fall into any kind of extremism, I'm fine sharing this forum with them. Diversity of mind is a good thing and I like reading opinions that are contrary to mine. I may oftentimes not agree with their opinions, but I'm nevertheless interested in hearing their arguments. It allows me to reflect on my own and to hone my debating skills. I don't think that people who are conservatives or right leaning are automatically evil and need to be purged. Conversely, your political affiliation with the left doesn't automatically make you a good person either.
That sort of political hate needs to stop, but most people are too busy making grand assumptions about strangers on the internet based on a couple of comments. That mindset alone generates more toxicity than any argument or heated debate ever could.
