I'm not stating she wasn't in pain and I'm not stating she didn't complain about being a hexenbiest. But what I read is that posters somehow take her complaint and her pain and then say she's lying when later on when she says she likes being a hexenbiest. Nick didn't like being a grimm at first. It can be taken further and stated that Wu didn't like being a werewolf at first. Juliette didn't like being a hexenbiest at first either. But they all liked it as they got used to it.
The best way to frustrate a cyberbully is to ignore him.
