I celebrate the holidays just fine. Yule, Ostara, Samhain, etc...
I think the commercial capitalist exploitation , in the guise of christian religious holidays like christmas, easter and thanksgiving, are representative of the material identity we have adopted to replace what at one time was a true spirit of the turning of the wheel of the year. It's now become a matter of gluttony and materialism. Gone are the days when one need not have a single present to unwrap, but instead were satisfied with the blessings of loving and healthy family and friends to celebrate the autumn harvest, the winter solstice, Beltane and the summer solstice. Instead our desires to give life to that old cliché' , he who dies with the most toys wins, causes us to see the pending celebrations on our calendar as an excuse to ring up charge cards and fatten the coffers of the USPS and on-line retailers, so as to impart our devotion to the tradition by the amount of goods and services we can impress ourselves and our loved ones with, when the special day finally arrives.
I use to work the shoe department of a large retailer. It was amazing to me how people in that particular department would clamor for just one more gift. One more object to wrap and snug under the tree. Whether it fit or not! One woman , I can still recall because it was pathetic, bought a pair of shoes
knowing they were a size to small. She reasoned herself into spending this money by saying to her shopping companion that because the shoes were made in such a way they would stretch and eventually fit their recipient.

And she probably wonders why people call her aunt Susie pigeon toe, to this day!
Suffice to say this same woman returned those ill fitting shoes on black Friday. I guess her aunt didn't feel like walking around in boots one size to small as she hoped they would stretch to fit and thus satisfy her nieces desire to impress her with one more wrapped box on christmas!
In any event, that's my take. And no, I don't celebrate christmas. I give to the ones I love year round. If I see something I know a family member or friend will like, I buy it for them. I either give it to them asap, or if it's on the calendar I wait until their birthday. Which I do celebrate because it is my gift that they were born on that day so as to gift my life for knowing them. That, in my experience, is the spirit in all giving. Love, appreciation, compassion and community.
