As others said, she's rude and often insufferably "woke", thus had a tendency to get under peoples skin when she was active, esp since Bog would reblog some of her annoying arguments. Even if you agree with aspects of her hard left politics, she had a habit of being a confrontational asshole about it. To be quite honest, if she weren't tied to someone as popular as Bog, she'd be just another boring, jerkass "enby" girl who can produce some ok-ish art.
I can only find a scant few examples, as she's very good at purging her old content, but hopefully these will give you a picture of how she conducted herself while she was active online:
- The "there are literally no feminists who actually 'go too far' or get 'too extreme." quote from the OP literally references a post in which he says the aforementioned quote while defending Rev, who is defending a feminist who shot a man and implies that the victim was at fault for said woman trying to kill him as he "pushed her too far as a friend", whatever that means.
- A tumblr user accurately describes her as a "caustic, hostile asshole" (archive) on a post where she argues about King Deedee. (archive)
- Though this comic is edgy, Rev's unsolicited response to it is rude and unnecessary, and it's funny how Bog jumps to defend the hive queen after the artist gives Rev some much-deserved snark.
- You are automatically bad if you are cis. (Also lol @ troonish foreshadowing.)
- Getting her panties in a bunch because a certain beloved piece of classic fantasy literature had elements of racism in it that were considered socially acceptable in the era during which it was written.
On a side note
this post did not age well lmao.
