I noticed there are male death and female death tags. Together they have over 3000 uses, but no implications. Do we need these, or are they overly specific?

I think that's too specific, yeah. I think generally if you're going to be searching for a particular gender, you'll already have a gender tag in your search. If I want a particular gender in a particular situation, say a man washing the dishes, I never think "oh surely I can squeeze both the sex and the action into one tag to invent a male_dishwashing tag", I'll just do the normal thing I do and search "male dishwashing". I really don't think death should be any different, plus the wikis for both tags are literally identical with only the gender to show they're different.

Usually, if you are doubting the validity of tags, check and see if they are solely populated by one person.
In this case, male_death & female_death are the handiwork of @beedrill77 and nobody else seems to be using those tags.

Should they be aliased to <gender> or to death?

Death

Definitely death

I tagged with female_death sometimes because I noticed them on the list with so many hits and I thought it's an established tag, thinking that maybe some people are more bothered by deaths of women more and would want to blacklist it, but not death in general.

The bulk update request #11662 is pending approval.

create alias male_death (1002) -> death (19995)
create alias female_death (2213) -> death (19995)

Reason: As suggested.

I'll have to agree that gendered death tags are not really necessary.

Alias the full set while you're at it
male, female, gynomorph, andromorph, herm, maleherm, and intersex

I know people in the snuff community have gender preferences but I think these are just tag bloat, so I think it’s fair to alias them

I don't think it's necessary to have gender-specific death tags. But, I can totally imagine some sick mofos with death fetish finding such tags helpful xD

honestly, thinking about it, kinda feel like an <x>_snuffed might actually make sense as a tag group while <x>_death does not. there's something about the intentionality of it that makes it feel more tag-like.
