That was just my guess/speculation, it's an artsy type of hobby (even if it's only mostly on the consumer's end of the art) so I can see that skewing left. As opposed to maybe a video game chatboard or sports talk. While I suppose we've never had much of a balance politically for posters on this line of threads, it's gotten worse since the changeover and the banning at the drop of a hat. Also, and here my bias may be showing, most of the conservative arguments on these boards tend to be insulting and emotional and without much in the way of an actual argument or logic. When people on the left call them on that the reaction it's usually to insult back and forth for a bit and then retreat.
Why I've praised you in the past, because even when I (or others) disagree with you there's usually an argument given and the logic behind what you're thinking (whether, again, we agree with it or not) and you're much more likely to be insulted than to give insults. And I'd say there's plenty of emotional and illogical arguments that reflexively defend some politicians and policies on the left/center, they're just less likely to be called out because of the political makeup of the people posting. You can also get the same insult for insult or a kick-circle of insults attempting to silence someone going against the narrative. Why I try to point that out when I see it, it's not great behavior and not a good look for confidence in one's argument.
I get being upset, there's been a lot in the last four years to be upset about and we're not even to the hard push to ban abortion rights or seeing the outcome of voter suppression, but it's better to take a beat and articulate the best argument for what you're thinking with as little insult or emotion as possible. Insults and emotion make it a lot easier to dismiss an argument if someone isn't inclined already to agree with you. Logic/rationality might not make them agree with you either, but it makes it harder to dismiss outright as they're going to want to do (few like having their beliefs undermined or questioned).
