Identifying the Problem: Prejudices

I wanted a checklist to look over periodically to check my cultural biases, so I'm making a list (and you can help me check it twice).

What is a prejudice?

A prejudice is a preconceived opinion which is not based on reason or experience. All prejudices are based on errors of fact and/or logic. If a property of some class is valid and the consequent is sound and it doesn't make or imply a value judgement based on these properties, then it isn't a prejudice.

This is NOT ranked or ordered, but here are some of the predominate types of prejudice I was able to identify. Please feel free to point out more in comments!

• Racism
  
• Sexism
  
• Gender-identity, sexuality, intersex (including LGBTQ*)
  
• Religious discrimination (including against those who choose not to have a religion (especially in the military) and minority religions)
  
• Ableism (discrimination against the disabled)
  
• Mental Illness / Neurotypicalism (multifaceted)
  
• Intelligence (people across the spectrum suffer discrimination & bullying)
  
• Appearance (height, weight, looks, dress)
  
• Linguistic discrimination
  
• Ageism
  
• Classism/socioeconomic discrimination
  
• Nationalism
  
• Rape, Abuse, & Violence stigma
  
• Political discrimination
  
• Discrimination against former felons
  
• Prohibitionist prejudices (assuming that all people who wish to explore altered states of consciousness are 'drug fiends', etc)
