Austin Cline has an article about how to blog more effectively about atheism, philosophy and religion. Most of it is sensible advice whatever you are blogging about. It also points out the importance of getting honest views out there. It's far easier for many religious people to create straw men out of us than it is to engage properly (funny, they also condemn worship of false idols...). 
Hence how, in the last few months, as the batallions in the "War on Christmas" have been slaughtered by Bill O'Reilly's sword of petty righteousness, we've seen the stereotype of the "Offended Atheist" pop up. The Offended Atheist is the non-believer who objects to religious verbiage and symbolism because it offends them. They oppose "In God We Trust" because it offends their atheist sensibility.
The Offended Atheist can then be dismissed quite simply by saying "Don't be so silly and so Politically Correct - Jesus loves you!". But the objections to the uncritical acceptance and endorsement, by government, of religious crapola like publicly-funded Nativity scenes does not stem from "offensiveness" or "political correctness". It comes from the feeling that the government should stay out of the religion business.
It comes from a strong support for secularism. I don't want to see religious endorsements by government, because it's not appropriate. We all pay for government, regardless of our religious belief. It has some tasks we have given it (if you believe in the social contract - I personally don't, since it's the contractual equivalent of vapourware - it doesn't exist!), and it should try and do those. The rest of us can erect Christmas trees and set up nativity scenes.
In my area, there are two big Christmas scenes set up each year. One is a Nativity scene, set up in the front window of a house by the old woman who lives there. I remember walking past there as a child, and seeing it there. She collects for charity and has a box outside the window for people to drop some cash in there. There is another, which is rather more gaudy and profane - with dancing Santas and reindeer and a very Hollywood nativity scene. This also collects for charity.
Have I, the local friendly atheist, been knocking on their door telling them how offensive these scenes are? Of course not. Get a grip on reality. I actually quite like them. But, at the same time, I support secularism strongly and avidly. If they were government funded, I would have complained. It's not the religion that 'offends' me. It's the combination of government and religion which annoys me. And, whatever your religion, it should annoy you too.
