The New Mass is a danger to your faith. The proof is the huge apostasy that has taken place since Vatican II.
Go look at the statistics for the Catholic Church over the past 80 years. You see a sharp turn downhill right at Vatican II. If they doesn't convince you that there's a "Crisis in the Church" necessitating participation in the Traditional Movement, then nothing will.
So-called "Catholics" don't even know their faith anymore. With a few rare exceptions, they don't practice any Catholic customs (scapular, indulgences, litanies, daily Rosary, Confession, fasting, abstaining, etc.), they are ignorant about the Faith, they practice contraception, they go along with liberal agendas (anti-death penalty, pro-open-borders-immigration, environmentalism, tolerance for sodomites, etc.) while being complacent about contraception and abortion. NOT acceptable for someone claiming to be Catholic.
The list of anecdotes could fill a volume of encyclopedias. Just recently a distant relative took her slightly older sister out to lunch on Good Friday. They stopped at Bill Miller Bar-B-Q thinking they had fish (they didn't -- they should have known better, since they were born in this area). Then they just ordered chicken, after the sister said, "Oh well, I'm over 65 anyhow." Problem 1: That doesn't excuse from abstaining; just from fasting. Problem 2: That would go for those over 65, not the distant relative who was several years younger.
So just in this one case, you have 2 Novus Ordo Catholics, taking that "twice a year fasting/abstaining" and easily converting it into "never". No mortification, no fasting. They completely fit in with the modern world, which is all about enjoying life (including Bar-B-Q) and has no use for sacrifice, mortification, and fasting (unless it's for health reasons, or to loose weight to get a great Bod -- then the World makes an exception! Hedonism can use that, after all...)
Just think of all the environmentalists, animal rights activists, etc. who do without meat or fast ALL THE TIME because they happen to be somewhere that doesn't offer vegan options? And now Catholics can't even fast twice a year. Pathetic!
When something is reduced to twice a year, it's almost impossible NOT to end up rounding-down to 0 (never). Whether it's going to confession, going to Mass, fasting, exercising, or anything else. When you don't have the habit, you're not magically going to drum up the habit every 3 months or something. No, once something feels like "never" it's going to stay perfectly "never" indefinitely. It's a big deal at that point. Something fun like a vacation or a birthday party, THAT you can do just once a year -- you're not going to skip out on fun, even if it is a big deal for you. A once-a-year birthday party is a big deal, but you happily go through that because it's fun. Fasting or going to confession? Not so much.
Just for starters, if you never fast or abstain, you're not going to know how to do it. You'll have no meatless dishes in your repertoire, you won't be used to eating anything meatless, etc.
That's why good habits (prayer, confession, exercise, study, work, etc.) must be learned, and early.
