Put them up or don't, think of it as a religious holiday or pagan, do whatever you want. I'm not going to worry about it whichever way you choose.
I'm still going to overdecorate and enjoy the heck out of it. That way I get the house cleaned twice in a year. I have to clean to put the decorations up, and when I put them away, I have to do it again. This way I am happy about it both times.
And I want you all to enjoy the midwinter any way that suits you. So have a Happy solstice when it comes.
