Aliasing rape_my_childhood -> invalid_tag.

Reason: forum #21433

Hm, the only person who ever used the tag is toboe.

Seems like null gave him a neutral about it but didn't delete the tags.

To be honest, I'd be in favor of invalidating all the *_childhood tags (rape_my_childhood, ruined_childhood, and there_goes_my_childhood. They're sort of stupid, silly tags.

I think rape_my_childhood should be aliased to there_goes_my_childhood. It's a fun tag and sufficiently like what_has_science_done to justify it's existence.

Difference between what_have_science_done and rule_34 (and all similar) is that effect of latter can be replaced by searching any particular cartoon/game/other from your childhood instead.
This argument was mentioned in forum #21433, and

Having a rule_34 tag is like having an animal tag. We're better off without it.

Same goes for all *_childhood tags.

B-but... muh joke tags...
