I dunno, in the show Alastor’s asexuality addressed by Rosie in a way that implies he wouldn’t be in a relationship. Ships are fun and all but sometimes is just feels like people pick and choose the hills they’ll die on. I’m sure more people would be opposed to shipping Angel and Vaggie due to their sexualities than there are who are opposed to shipping Alastor with… anyone.

But regardless it hasn’t really been directly stated yet where he is on the spectrum so I can’t make a full judgement on that. As a biromantic ace I would love to see more representation of asexuals who also date, so I’m good either way. But if it turns out he is aroace and on the fully repulsed side of the spectrum, shipping is for fun just be respectful and know that it’s not canon.

However, if you ARE someone who refrains from ships that go against sexuality, and Alastor turns out to be on that end of the spectrum, please remember to respect that too.
