Your post is so far off base it isn't even funny. I AM a Christian, but what part of "secular nation" eludes you? No one has to say the Pledge (except public school children in some states as a result of 9/11), and I do omit the "God" from my recitation of it because I do not believe it is right. Just because there's a Christian majority doesn't mean we have the right to step on Hindus, Athiests, Buddhists, and other religions that are not part of the Judaism-Christianity-Islam trio.
Why would I be offended of Allah or Moses (BTW Moses is part of Christianity, too, in case you forgot)? I would be offended if the Pledge said "one nation, under Allah" because I am not Islamic, and therefore would feel excluded in a way from the nation. The Pledge is about unity. How can one unify when one set of beliefs is clearly favored over another?
This "small group of people trying to impose their will on the majority" is just fighting back for the majority unconstitutionally imposing its will on everyone back in the 1950s; it's righting a wrong.
BTW you are wrong regarding the nativity scenes; cities can display them as long as they provide an "open forum" for all religious displays. Most cities just stopped with the nativity scenes when the Wiccans started showing up due to prejudice there.
As far as Xmas trees in college dorms...well they are a big fire hazard so no issue there from me! I'm sure a student could erect one in his room if it were not a fire hazard, but what is most likely frowned upon is erecting one in a public area.
Seeing as Winter Recess typically lasts a month (give or take a week) "Christmas Vacation" is a misnomer anyway. Why not New Year Vacation? or Holiday Vacation? Seeing as we already have Summer Recess, Fall Recess and Spring Recess, Winter Recess just fits in with the others. Honestly, you're free to call it whatever the hell you want to call it, but anything publicly-funded must stick with the secular term.
Please, don't argue with me and use a bunch of useless emotionally-based rhetoric because I will rip it to shreds. Use facts. They are a lot more effective.
