Trid is presenting his tired old "you are only Catholic if you agree with EVERYTHING the magisterium says". Differ by one iota, and you are not truly Catholic.

Trid does not accept "the hierarchy of truth" -- I would prefer to call it "the hierarchy of teachings". Some teachings are more significant than others. To claim the teaching on contraception is as important as the teaching on Christ's divinity is silly.

He is reading most of the American Catholics out of the Church. It is estimated that 90% of married Catholics in the US and Canada of childbearing age have used contraceptives. Clearly, this is a teaching that has been firmly rejected. 

Something that Trid denies, the magisterium has changed teachings. For example, Pius IX condemned freedom of religion several times, Vatican II said it was a right of all people. So when teachings change, do you go with the old or with the new?

He is really saying, "Those who disagree with me are not Catholic".
