Lemmy.ml and even more so lemmygrad.ml (the latter is defederated from by most sane instances across the Threadiverse) are tankie platforms. Tankies believe in alternative facts, such as the fact that nobody died in the Tiannamen Square Massacre. Or if they did then they deserved it. Or if they did not then it was necessary. Or if it wasn't then... - I am saying that you should expect arguments to shift goals moment to moment, based on the personal biases and need to appear right on the Internet, regardless of any need to actually be thus.

And don't even get me started on hexbear.net, which has no real beliefs at all beyond the raw need to troll people incessantly (this one is also defederated from by nearly all sane instances across the Threadiverse).

So, you are missing out on nothing important whatsoever. Consider yourself fortunate that you discovered this early on.
