Category talk:American space opera films

Shouldn't American science fiction films come here as a subcategory?
I'm not gonna make a big deal about this, but I find that it would make more sense.--Taeyebaar (talk) 01:39, 14 March 2016 (UTC)
 * I'll add it as a supercategory. Subcategories are for more specific categorization, not less. All American space operas are American science fiction films, but not vice versa. DonIago (talk) 01:59, 14 March 2016 (UTC)
 * thanks for your responses and clarification. User:Gothicfilm removed it without explanation and did the same on multiple pages. You might want to keep articles that belong in that category on your watchlist in case that user removes them again. Let me know if it happens again and I'll report for vandalism.--Taeyebaar (talk) 21:11, 17 March 2016 (UTC)
 * Honestly, I think you should try to engage Gothicfilm (who I considered pinging) at an appropriate Talk page before reporting. Removing a category does not constitute WP:VANDALISM and if you report them on that basis you risk a WP:BOOMERANG. It may be disruptive editing, but an effort should be made to determine their reasoning rather than assuming bad faith. Cheers. DonIago (talk) 13:55, 18 March 2016 (UTC)
