Meg says that "Like and equal are not the same." What does she mean by this?

These are
such great books! 

I'll go further by clarifying the semantics of Meg's
comment and expounding on the answer you first received.  The words "like" and
"equal" do not have the same meanings.  For instance, in the 1960's in America, black
students went to school "like" white students, the had public water fountains
"like" everyone else, and they could ride public transportation "like"
everyone else.  However, these were not "equal" circumstances. Black schools lacked
needed supplies and resources like books and qualified teachers, water fountains for blacks in
public were only for blacks--they may not always be serviced or working properly or kept clean,
and blacks were expected to ride in the back of public buses and even give up their seats when
the bus was overcrowded to white passengers.  "Like", yes, but
"equal"?--absolutely not.

Now, go back and read the section where
Meg makes her comment and see if you follow better.

Good
Luck!
