The Roman Catholic Church likes to present itself to outsiders as one whole unified edifice,however for those either inside the church or former members the experience is significantly different .
The constant jockeying for power within the church by various groups belies this idea of uniformity of doctrine ,you only need to be aware of the hatred shown by for example the Jesuits towards Opus Dei and vice versa over matters of doctrine to appreciate this and this is just one example ,Franciscans and Dominicans are often at loggerheads not only with each other but also with other Orders.
It tends to be recent converts to Catholicism who adhere most strongly and most compleltely to doctrine on things like birth control, existing long standing members on the other hand tend to be a bit more a la carte using the principle of "What the Pope doesn't know won't hurt him "
The Republic of Ireland is however an exception to this rule.
The traditionalists such as the Confraternity of Catholic Clergy in the church are fighting others within the church to retain the provisons on birth control in Humanae Vitae (1968) is just one example of differences in the church.
The very fact that they have to openly state this just shows that there is a major disagreement within the Church.

"Catholic Clergy Challenge Colleagues to Reacquaint Themselves and Their People with Humanae Vitae
Contact: Rev. Fr. John Trigilio, Confraternity of Catholic Clergy, 717-957-2662
BALTIMORE, Maryland, July 19 /Christian Newswire/ -- The Confraternity of Catholic Clergy celebrated the 40th anniversary of Humanae Vitae, the encyclical from Paul VI, by asking every deacon, priest and bishop to reread and re-educate their flock with this prophetic document.
The organization also pledged support for all bishops who confront and deny Holy Communion to unrepentant Catholic politicians that support abortion, if prior attempts to enlighten their consciences fail.
A national association of 600 priests and deacons, the CCC met in Baltimore, MD, July 14-17 for its 33rd annual convocation. Dr. Janet Smith, Fr. Thomas Euteneuer (HLI) and Fr. Peter West (Priests for Life) and Mr. Thomas McKenna were speakers.
All of them discussed the perennial truths taught in Humanae Vitae, namely, that human life is sacred from the first moment of conception until natural death and that it is gravely immoral to separate the unitive (love) and procreative (life) ends of conjugal love. Hence, abortion, contraception, in vitro fertilization, et al. are considered sinful and immoral and to be avoided.
Dissent from Humanae Vitae, which was in vogue in the late 1960's is on the decline in Catholicism since the pontificates of John Paul II and now Benedict XVI. While sometimes a difficult teaching to embrace and maintain, it is nevertheless the only means to uphold the natural law and to safeguard the sanctity of the human person, marriage and the family as well as civilization itself.
Forty years ago, opponents of Humanae Vitae wanted Pope Paul VI to change the Church's ban on contraception due to the then newly developed birth control pill. Experts point out, however, that since the advent of the Pill, instances of breast, uterine and other forms of female cancer have increased in proportion to the proliferation of the Pill. Sexual promiscuity, deviancy, venereal disease, increase in divorces, illegitimate births, and a host of other social ills threatening society and the Church.
The CCC challenges all its brother clergy to teach, explain and defend this most timely encyclical.
A plea was made to the national conference of bishops (USCC
so that an accurate and eloquent English translation of the Roman Missal be approved expediently as long as it does not insult the intelligence of the faithful and does not betray the authentic Latin text. The CCC thanked Pope Benedict for his visible efforts to restore more reverence to sacred worship through personal example when celebrating the liturgy."
There is also dispute between this group the CCC (which may be a front for Opus Dei ) and a group of nuns called NCAN National Coalition of American Nuns regarding the words used in religious services ,petty maybe but certainly not a sign of complete consensus as to what the Cathloiuc church is and should be .
Regarding current Catholics or ex-Catholics being "responsible" for the Inquistion,then surely Protestants must be equally held responsible for the Salem Witch trails etc etc etc
and BTW I am a practicing catholic.. but even I dont follow exactly the teachings of the church.
