What can be done to return to the people the notion that there exist Christ, His Church, and yes - FASTS... and that it is blatantly un-Christian to engage in festivities and congratulations on the days of the Holy Week with its strict fast, mourning, spiritual silence?
First off, let me assure you that I understand where you are coming from. The world in which we live in is so divorced from that which we know to be right, true, and beautiful it causes my heart to ache.
But, when faced with these dilemmas that are only dilemmas because we choose to live a Christian life, then we must turn to the foundation of our Christian life to solve these problems. We need to love those we meet who have forgotten why we celebrate Pascha, and love them so much that they realize they want to join us in that love.
Because love only invites and never compels, we need to love those folks into joining us becoming living examples of Christians. This means all of us should never give in to despair or be discouraged, but instead we need to:
-Pray for those who truly do not know what they are doing is not right by concentrating on the Springtime that Easter falls in, instead of the new rebirth that the Resurrection brings us. Because prayer is love in action, prayer is definitely the right thing to do.
-We also must remember to fast, because fasting helps us to love (as you know from my endless and repetitive sermons!). Fasting also sets us apart from others and may help prompt questions from those who don't understand how important it is for us to do this, and then we can introduce them to Love Itself, who is Christ.
-And, give alms as we can. This is also love, and besides taking care of those who are fiscally disadvantaged, we also need to include those who are spiritually disadvantaged, such as your friends who just don't know that there is more to Pascha than happy birds and brightly colored eggs. The Spirit will create an opportunity for you to share with you your faith sometime in the future, and when doing so remember to be loving as you share, and not authoritarian.
You are not an authoritarian person, Heorhij, but sometimes when we are asked about our faith we fumble things by becoming all 'high and mighty' and sounding like we are experts in this topic, when all we are is messengers, not the message itself.
Never give up, Heorhij, because if the foundation of our Christian faith is love, then hope also follows. Despair should be foreign to us, and so we have to keep trying to love, even to our last breath.
