That's it in a nutshell, really.
Religion is basically about two things - it's about something that you believe in, and it's about something that you do.
But Christianity in the West has been neutered by creeping secularization. All the traditions have been secularized ("Christmas should be for everyone! No religious themes, please", etc.) or have simply been erased alltogether (even among Catholics, how many are aware what Lent is? And your average Protestant doesn't even know that things like fasting and pilgrimage were originally very important in Christianity).
Mainstream Christianity in the West has been reduced to something that has no impact on everyday life whatsoever. It's no longer something that you *do* - it's been reduced to just an abstract belief that has little relevance to anything at all.
On top of that, the general public - a lot of mainstream Christians very much included - is ignorant of Christianity and its traditions. How many regular people could tell you the difference between Easter and Pentecost? So celebrating Christian traditions won't strike a chord with outsiders. They'll just think it's weird, or it won't even register.
My favourite example of that is when some Catholic Hollywood actress (I can't remember which one) decided to fast for Lent the traditional way - i.e. no meat, no dairy products, and no alcohol for 40 days. Yet what did journalists make of it? "She's going vegan for a month!"
Another impediment is that the general public's opinion of Christianity and Christian history is exclusively negative. The fact that their knowledge of both Christianity and Christian history are very limited reinforces this. Point out something positive about Christianity, and people will either accuse you of lying (even when you're presenting very clear evidence) or default to whataboutism. Sadly, many mainstream Christians will join in with that, because they are both ignorant and have been conditioned with a secularist worldview.
This combination of ignorance and negative views of Christianity is a particularly persistent problem. Of course, the Bible already tells us that the world will hate us (Matthew 10:22, for example) - but that doesn't mean that we should just sit back and do nothing. Honestly, I'm not sure how we can best tackle this particular problem. Though prof. George Yancey did some very interesting research into prejudice towards Christians and Christianity, so looking further into that might yield something.
As for these problems in general: I would say that the best approach is a combination of a return to the fundamentals of Christianity and working to recover dwindling or extinct Christian traditions.
