[Maximilian]

The Masses they celebrate are also valid, but it is considered morally illicit for the faithful to participate in these Masses unless they are physically or morally impeded from participating in a Mass celebrated by a Catholic priest in good standing (cf. Code of Canon Law, canon 844.2).

So it is NOT morally illicit to participate in an SSPX if you are morally impeded from participating in a New Mass travesty. It is morally impossible for me to set foot in a New Mass church. I don't mind attending an indult Mass if it's available, but it's not necessary to have an indult, and it IS morally necessary for me to attend only the true Catholic Mass of all time.

Clearly. Given a choice between a gay parish and the SSPX, what choice have you?
