That page is not the same: it lists crimes of the same type, not by the (supposed(^*)) ideology they were committed under.

There are a lot of ideologies in the name of which mass murders were committed: fascism, Christianity, Islam, other religious ideologies,... and some ideologies for which this is at least debated, like capitalism. The problem is that these crimes often vary so much that it's hard to find a common thread besides vague ideological motivations. So it is less controversial to group them by the type of crime, like killing of indigenous peoples, regardless of the supposed justification (religious, economic, racial...)

Are there other Wikipedia pages in the style of "mass killing in .*ist regimes"? I couldn't find one.

* I write "supposed" here in line with the discussion in the original article where the question of what classifies as a communist regime is discussed a bit.*

I agree that it's hard, but some scholars have argued that there is a common thread. Why wouldn't we want to put that scholarship on Wikipedia?

There's this, but it's not well developed.
