Surely everyone acknowledges that society isn't equal. People are disadvantaged over race, sexuality, gender, class etc.
Take something like political correctness. I find it mystifying that some people object to not being able to joke about something that offends someone else, and even takes that a step further by blaming that person for being offended.
As long as people are not breaking the law, they should be able to live their lives free from any discrimination and should not be disadvantaged in any way. Society will never be completely equal, but we should never stop striving to improve equality, so society becomes more equal.
