taking offense

my mom recently was called as a member of the relief society presidency.
in her first email, she was asked by the priesthood to inform the sisters of a service project for the men of the ward.
afraid of offending the single sisters, rather than telling the women to inform their husbands, she said: " This was sent from President Oliver to go out to all of the sisters. Maybe so you can remind your husbands, sons or brothers!"
a single sister in the ward instantly replied: "Thanks for the notice, but I doubt I will be able to remind my husbands, sons or brothers."
my mom brushed it off, and cleverly replied: "Sister, you have so many brothers in the ward!!! "
however, the email raised a question in my mind that i have been thinking about for quite awhile: why does our society feel the need to take offense?
why must we filter through every comment, and even act of service to be sure that there is not some tiny category of people that we have offended?
in school, often if there is one child alergic to chocolate, the teacher often informs the entire class that they may never bring chocolate to share, because of this one child. But that is just a tiny example of a much larger problem. in school, i feel like mentioning God is worse than saying a curse word, because some of us might not believe in God. according to FOXNews.com, 92% of Americans believe in God! 92%! so wouldn't the 8% be happy to learn about the religion that they are surrounded with, and that our country was founded on? history teachers skip over mentioning God as the motivation for Americans in founding this country. have these teachers ever attended washington d.c.? the founding fathers and other early presidents give no hesitation in mentioning God as their motivation. that absolutely does not mean that they did not accept people who do not believe in God. this is a country where we follow God's commandments. on march 30, 1863, President Lincoln proclaimed a national fast day as a call to bring Americans to repentance. he said: "Whereas, the Senate of the United States, devoutly recognizing the Supreme Authority and just Government of Almighty God, in all the affairs of men and of nations, has, by a resolution, requested the President to designate and set apart a day for National prayer and humiliation." the full speech can be found at http://showcase.netins.net/web/creative/lincoln/speeches/fast.htm
why are christmas trees completely banned (we are only allowed one tree that we are not allowed to call a christmas tree, but a "giving tree) at school, let alone nativity scenes, when according to worldnetdaily.com, 96% of americans celebrate christmas?? it is a national holiday and a part of our culture. i don't understand why the possibility of offending 4% of people should cause us to ignore the culture of 96% of them.
in America's quest to "celebrate differences" the only differences we seem to celebrate are anything that deviates from the majority.
