That is a real stretch.
Eternal Life is given freely by God Almighty who gave us a Way - Jesus Christ.
We are not worthy of this Gift of Grace, yet it is given.
Celebrating Easter as a representation of the Crucifixion and Resurrection of the Living Christ does not deny someone the Gift of Salvation.
Celebration of CHRISTmas as representing the Birth of Christ of the Living Christ does not deny someone the Gift of Salvation.
People choose Christ or they don't, they do so of their own free will, Easter and Christmas have nothing to do with the lack of Salvation.

God said He hated all the feast days that He didn’t institute. It’s impossible to get around that.

.
Celebrating Easter is worshipping another God. It is also disregarding the commanded observance of Passover. YHVH tells us what to celebrate, and exactly when to do it. Easter and christmas deliberately violate both.

Deliberate sins require repentance.
