Apples and oranges.  According to the Church, straight folk can get married and thereupon have married sex without sin.  Gay folk, on the other hand, have an intrinsic disorder, or whatever the hateful language from the hierarchy is currently, and never get to have sex without sin.  Their lot is to lead a blue balled celibate life.  It a nonsense to see an equivalency of moral standards in the way the Catholic hierarchy views gays and straights.
Ironically, given the theme of conscience, I suspect that many gay Catholics use the primacy of an informed conscience (as per the Catechism) to ignore the current hierarchy's inconsistent teachings on gays (gays=good/gay sex=bad).  Just as many straight Catholics do the same thing with contraception, etc.
Strange that the folk, who attacked the critics of the Pope's meeting with Kim Davis, have now gone silent, when the Vatican distanced the Pope from Kim Davies and effectively indicated that those critics were right.
