Good points! And I'm really glad you pointed this out. I'd say that summoning could be considered fairly neutral, dependent on the summoner. Willow does it all the time in s6 & s7, what with the Hecate and D'Hoffryn. It's Tucker that exemplifies it as malevolent skill, with The Prom. But it didn't have to be, even if the opposite of demon "summoning" would be demon "dispatching." Which is obviously Buffy's job. By the time Andrew rolls around, summoning seems to just be considered his little rarely-needed niche in the Troika. But he's not really ... you know, summoning anything. He's probably less powerful with the magic than even Jonathan. (Which, incidentally, I watched Superstar last night and I really like the fanon-created idea that the guy in therapy that Jonathan got his altered reality spell with was either Tucker or Andrew.)
