MCCARTHY ON THE CHARLES: Harvard professes to be so concerned about discrimination that it has literally set up a blacklist for students found “guilty” of joining off-campus single-sex social groups such as sororities, fraternities, and “final clubs,” making a mockery of freedom of association. The Harvard Crimson today reports on efforts in Congress to preserve this freedom, and Harvard’s counter-effort. This after Harvard blacklisted gays in the 1920s (driving one student to suicide) and Communists in the 50s. Now that institution, whose wealth would embarrass Scrooge McDuck, demands the right to continue to receiving federal funding while persecuting sorority girls. Have you no sense of decency, Harvard, at long last?
