Yes it does. Touhou, Undertale, frickin Steven Universe, they're all doing it. Crossovers are a way to show your appreciation for both universes.

Stop being a whiny killjoy and repurpose this anti-crossover hate group into something worth a damn already.

Now, we just need a group for, "Not every pairing needs a clopfic" and we'd be set.

I approve of this group just on general principle.
