Tolerance And Politics?

I saw a question just recently that asked why liberals should tolerate "intolerance" and made me think: do these types of people actually understand the definition?

Tolerance:

1.The capacity for or the practice of recognizing and respecting the beliefs or practices of others.

2.Leeway for variation from a standard.

3.The permissible deviation from a specified value of a structural dimension, often expressed as a percent.

4.The capacity to endure hardship or pain.

5.Physiological resistance to a poison.

6.The capacity to absorb a drug continuously or in large doses without adverse effect; diminution in the response to a drug after prolonged use.

7.Acceptance of a tissue graft or transplant without immunological rejection.

8.Unresponsiveness to an antigen that normally produces an immunological reaction.

9.The ability of an organism to resist or survive infection by a parasitic or pathogenic organism.

As can be seen, the definitions are wide ranging but they amount to the “tolerant” person (or group) giving their permission for a deviation from the norm (#2). If we take Yahoo! Answers as a measure, a vast majority of liberals demand “tolerance” as defined in #2, but refuse to provide the definition in #1. I find it to be arrogance in a major way as the presentation is thus: “if you do not agree with my giving permission for these different things you are a hateful person and no, I am not going to include your deviation from my perspective.”

When placed in the political spectrum, tolerance is a group of people stating that they will permit others to act as they choose so long as it is within their own views of right and wrong. If you disagree, they can and will attack you because, in their eyes, you are not allowing for their arrogant permission.

This is the generic liberal method, yet conservatives are the ones labeled as being hateful and arrogant.

Why would anyone with compassion subscribe to this level of thought?
