Depends on which branch of Christianity. Some Christians have nothing to do with Christmas because it is just a pagan celebration with a fake wrapping of Jesus. They might say anniversary of the resurrection instead of Easter (the date is correct if I understand the Hebrew calendar correctly - which I probably don't), and they would object to bunnies and other non-christian symbols of Easter. Those are the major holidays I can think of.
Most Christians of course don't, which is why we think of the above as Christian holidays even though some Christians find something objectionable.

The only “Christians” (the application of this label to them is controversial within Christianity) that take this approach are Seventh Day Adventists, Jehovah's Witnesses, and some related groups, who share the trait of rejecting the concept of holidays (with the exception of, or as distinguished from, the regular Sabbath). I know of no Christian group that rejects Christmas for pagan ties and refers to Easter in the way you describe.
I know of several other Christian groups today who don't. The ones you mention are the only ones anyone is likely to recognize without personally knowing someone in the church. It isn't only about rejecting holidays.
