So oppressed, so marginalised, so weak and vulnerable and in need of protection from women. 
This just proves that Magdalen's legacy lives on. They hate the fact that JKR referenced her, that people still watch her videos, that even after her death, she is still opening up people's eyes to the misogynistic bullshit. Actually they are continuing her job for her in that respect with these tweets.
These people have huge gaping holes in their lives that they fill with this stuff.

She is still achieving what she set out to achieve, even now
