Poster Priest for Vocations--Known Dissident?

Such is the claim at Life Site:

The ad pictures Fr. Marcoux smiling, with the subtext "Priesthood, I love
my life."

The only problem is that Fr. Marcoux was the main signatory and in fact
one of the promoters of a letter slamming the Vatican and the U.S. bishops for
using "vile and toxic language" in addressing homosexuality.

The diocese cannot claim ignorance of Marcoux's actions since he led
the charge to write the controversial letter to the US Bishops Conference, and
the Congregation of the Doctrine of Faith then and sent a copy to his bishop,
Rochester Bishop Matthew Clark. Bishop Clark has long been known to be a
sympathizer of homosexual clergy.
