Provide a quote from a credible source that backs up your claim: "most PROTESTANT colonies in the Americas had actually banned Christmas observances."
I read the wikipedia article. It says that christmas was rendered illegal (by law) in Plymouth colony (which was later incorporated into Massachusetts colony), Massachusetts and Connecticut.
So the above quote is a bit sloppy and innaccurate as most protestant colonies (all were except (mostly) Maryland) had not (officially) banned christmas (services) - Plymouth colony (later part of Massachussets), Massachusetts and Connecticut were not a majority of American (protestant) colonies.
And how many English colonies were there at that time? Certainylk not the '13'.
