Alright, so let’s apply this principle.
You seem to be posting from time to time to [!metal@lemmy.world](https://lemmy.world/c/metal ). Where is the alternative community on another instance you crosspost to?

Hm, I’m not sure you are aware, but I am among the ones pushing for
<li><a href="https://programming.dev/c/linux"; rel="nofollow">!linux@programming.dev</a> instead of !linux@lemmy.ml</li>
<li><a href="https://lemm.ee/c/movies"; rel="nofollow">!movies@lemm.ee</a> instead of <a href="https://lemmy.world/c/movies"; rel="nofollow">!movies@lemmy.world</a></li>
<li><a href="https://lemm.ee/c/interestingasfuck"; rel="nofollow">!interestingasfuck@lemm.ee</a> instead of <a href="https://lemmy.world/c/interestingasfuck"; rel="nofollow">!interestingasfuck@lemmy.world</a></li>
<li><a href="https://sopuli.xyz/c/map_enthusiasts"; rel="nofollow">!map_enthusiasts@sopuli.xyz</a> instead of <a href="https://lemmy.world/c/mapporn"; rel="nofollow">!mapporn@lemmy.world</a></li>
<li><a href="https://sh.itjust.works/c/games"; rel="nofollow">!games@sh.itjust.works</a> instead of !games@lemmy.world</li>
<li><a href="https://lemm.ee/c/casualconversation"; rel="nofollow">!casualconversation@lemm.ee</a> instead of <a href="https://lemmy.world/c/casualconversation"; rel="nofollow">!casualconversation@lemmy.world</a></li>
So I am indeed aware of what you are saying, and I agree to an extend.
But as I said, you still need a minimum amount of activity to keep a community, alternative or not, active. Dads and parents communities aren’t active anywhere on Lemmy yet, so it’s more important now to first identify people, and then allow them to move or split.
Star Trek communities seems to coexist and be active enough because the topic is popular enough among the Lemmy population. It’s not the case for every topic.
