Disappointing, even if she is now claiming that it was only a temporary rule in her class (still highly suspect.) I'm not sure I buy that girls need encouragement to play with LEGO. Do a little research and you'll see it is one of their biggest markets right now. LEGO has went hard after the girl market and the Friends and Disney Princess sets are among their biggest sellers. These LEGO toy sets are just as intricate in their building and creative experience, IMO (I think I know... I own a lot of them.)
If she wants to talk about equality though...
boys are two-thirds more likely than girls to have a learning disability.
boys are up to four times as likely than girls to have neurodevelopmental disorders such as autism.
boys are more than twice as likely than girls to have ADHD (up to 5x as likely according to some sources).
boys make up two-thirds of students in special-education and are 5x more likely to be classified as hyperactive.
Boys are more than twice as likely than girls to receive a prescription for antipsychotic medication regardless of age (to treat mental disorders, ADHD, etc.)
boys are 30% more likely to drop out of school than girls.
boys are outnumbered by girls in higher education later in life, making up 44% of bachelor degrees and 45% of graduate degrees holders respectively.

It doesn't stop there... you can find all kinds of worrying statistics about boys when it comes to their capabilities to learn and thrive in the classroom. Of course, our society is set up in a lot of ways to benefit males more, which is something we are continuing to address and improve on thankfully, but it doesn't change that the playing field is not level. While society may favor boys in a lot of ways, the deck is stacked against them academically. And teachers need to be sensitive to this.
Oh, and as a LEGO fan for ages I'd really be interested in LEGO's response to this if it starts to blow up anymore than it has. We do have lots of data that shows children who grow up with stimulating toys such as LEGO are more likely to go into STEM fields and other highly-skilled jobs, so I really don't think it's a trival thing to discourage any child from enjoying them.
