Ok, my beliefs:
That the most important thing for everyone is integrity. Everyone should strive to be a good person.
That all people are inherently good. However, people do bad things when they don't have the support or skills to do the right thing. Greed and envy can make people lose sight of the right thing to do, so therefore often people need to be reminded of what is right. It is everyone's responsibility to ensure that others know right from wrong. Humans should support one another, and should always make a special effort to support the vulnerable - this includes animals. When people are being unkind to others, we should step in and put a stop to it, to the best of our ability.
That education is the fundamental of everything. All children and adults should have access to a free, diverse and unbiased education.
That all humans should have the freedom to make any decisions that affect only themselves. Any decisions that negatively affect others should be examined to see where the balance between benefit and negative repercussions lies. Our laws should reflect this.
That the environment should be protected from our greed.
That all children should have a fair and equal access to resources - financial, educational etc.
That everyone should have access to a healthy lifestyle, including suitable accommodation and health care.
That all people should have equality of opportunity. There should be the harshest of penalties for sexism, racism, disablism or any other imbalance of equality of opportunity in the work place and public life. (This includes religion - for example all peers to be fully elected, not selected from Synod etc.)
That's all I have time for now, I could do a whole manifesto!
