So you think she was waiting for someone to call SB out for wanting "girly" Lego so she could cause a mini chaos and go viral again? Would explain why comments were open (see also tweets about JK Rowling)
Something did feel performative about her saying she's glad he's playing with Lego flowers rather than "H*rry P*tter" toys, as if she's still deliberately trying to stoke that particular Twitter fire. If you honestly feel strongly enough about a thing that you have to censor the name then just don't bloody tweet about it!
I think it might be a way to stir up some hate so that she can use the "See! They only hate me because I'm ~different~" claim to deflect any and all criticism.
