ok, so pre Troll-Reset, powers were there just not a lot. And only the rejects of society would have them.

Meaning Aranea would have been viewed negatively because she has “bad guy powers”

And post-reset, powers were all over. And they were used negatively, because the trolls in that reset were abusive assholes. So Vriska was viewed negatively.

Basically, none of these girls could catch a break.
