It seems too good to be true, but an eighth Harry Potter book will be available this summer. Harry Potter and the Cursed Child — based off of the script for a play of the same name, and the book is essentially the script in an accessible form — is a welcome return to the wizarding world for author J.K. Rowling. 

However, Rowling's presence has been felt in a similar magical world: Twitter. For years, she's championed for feminism and LGBTQ rights, taking out any ignorant cave trolls in her way. Here are some of her best Twitter moments.

Rowling has made it clear that Hogwarts was a very inclusive school — one that would accept any and all people, including LGBTQ students: 

She's supported the gay marriage legalization in neighboring Ireland: 

As a follow-up, she challenged the highly controversial and much maligned Westboro Baptist Church for honing in on her — and absolutely destroyed them: 

Additionally, Rowling has backed up Emma Watson — who, of course, played Hermione Granger in the movie adaptations of the Harry Potter novels — for her own public support of feminism during her speech at the United Nations New York headquarters in 2014: 

Similarly, when Rowling cheered on Serena Williams for capturing her sixth Wimbledon title, she defended the tennis star from a misogynistic tweeter, who said the reason Williams is successful is because she's "built like a man." That has, unfortunately, followed Williams around throughout her career, but Rowling had her back:  

Though the initial tweet she responded to has since been deleted, Rowling's sharp take on disparaging, hateful comments on misogynists works perfectly as a broad, mic-dropping takedown:  

As the author of one of the best fantasy series of all time, Rowling has a huge following on social media, and she's used it to champion and support important social causes. Finally, a note of caution for the trolls and misogynists: Don't mess with her, unless you want your verbal takedown illuminated in the digital space for all to see.
