No, no no. This community existed long before us redditors showed up and I'm all for adopting a new community but let's use the terms that have been here for years instead of showing up and taking over the place. There's no Sublems, Sublemmys, uplems or downlems. There are communities, upvotes, and downvotes. This site has been around for years, we've been here less than a week. Stuff like this is why Beehaw and others are defederating. Adapt to your new home, don't try to force those kind enough to take us in to adapt to us.
All good points, but speaking as someone who watched reddit change over the years, it's also not something you can change by being stubborn and insular. If newcomers are suggesting changes, it's only because they want to contribute to the place, and that spirit should be encouraged. There's nothing malicious in it, so it shouldn't be greeted with defensiveness.
