Opponents of Governor Andrew Cuomo's effort to legalize gay marriage in New York held a rally outside the Statehouse on Tuesday.

More than 350 people attended the conservative group New Yorker's Family Research Foundation latest Mayday for Marriage! rally. The group is crisscrossing the state in a bus tour modeled after last year's nationwide Summer for Marriage Tour 2010 sponsored by the National Organization for Marriage (NOM), the nation's most vociferous opponent of gay marriage.

At the tour's inaugural rally in Elmira, Rev. Jason McGuire, the group's executive director, likened passage of marriage equality to the 1973 Supreme Court decision Roe v. Wade.

“My generation asks the last, 'Where were you when they tried to redefine when life began?' The next generation will ask of ours, 'Where were you when they tried to redefine marriage? ' What will we say to future generations?”

One of the most extreme signs seen at Tuesday's rally warned, “LGBT Marriage KILLS.”

The rally comes a day after Governor Andrew Cuomo released a video message in support of the proposed legislation.

Key for passage is the Senate, where a 2009 gay marriage bill died without any Republican support. Democratic Senator Ruben Diaz Sr., the most outspoken opponent of the legislation in the Senate, headlined a rally in the Bronx last week.
