They:

approved continuing but limited affirmative action
struck down sodomy laws
upheld Internet filtering for schools and libraries
upheld California's three strikes law
upheld "Megan's Laws"
ruled that states could punish cross burning
held that RICO couldn't be used against abortion protestors
upheld a 20 year extension of copyright
ruled that a state may try to force drug companies to lower prices
ruled against Victoria's Secret

Some of these decisions could be defined as "liberal" and others "conservative."

Looks like a mixed bag to me. And as for Roe v. Wade, I dunno -- the sodomy decision seems to reinforce privacy rights.
