I'm not a Christian, but I can say that Jesus's birthday was not traditionally an important Christian holiday.
Easter is the big Christian holiday. Christmas was a season of revelry around the solstice, which got co-opted by the Christians, so if they complain that the "meaning" of Christmas gets lost in the other stuff, that rings hollow.
And of course Easter traditions (including the name) are just as pagan (or more-so) than Christmas traditions.
