I'm Liberal as you say, but having posters of Jesus in a school is an EXCELLENT thing in my opinion. Religion, whether it be Judaism, Islam or Christianity, teaches a moral code and ethics - far better than secular humanists do - as it gives a purpose and a feeling of wellbeing.    Little story: A Jewish boy entered his school and found a Christian Prayer group in the foyer praying each day. He asked his Rabbi what he should do, as he felt offended and left out due to being a minority (and the one that's always blamed for the death of Christ). The Rabbi told him to not be so self centered, and that the prayer group was an excellent thing - Jesus was a great man who taught many sensible and moralistic things, and that a gentile who was a Christian or Moslem was a lot more likely to do the right thing in a given situation than an Atheist due to the fact that atheists tend to be either Hedonists or Nihilists.    I consider myself Liberal on many issues, and Jewish, but Jesus doesn't offend me in the slightest. People who take offence to other's faiths are narrowminded in my opinion.
