I don't really see that you are asking a question. I definitely understand your frustration and your anger. However, I am not sure what legal advice you are seeking. To tell you that it is "American" or "un-American?" To be honest, I don't know if there is any consensus on what is American or un-American anymore. I think that it is each individual's personal perspective. However, I would hire an employment attorney to assist you with your appeal of the denial.

If you were seeking unemployment benefits from your previous employer whom you left to take another job, it is unlikely that you will win your appeal. With or without legal counsel, this is not a good claim because you chose to leave this employer.
If, on the other hand, you are seeking unemployment benefits from the new company, I would be surprised that your request for benefits was denied. If this is your scenario, you should look for an attorney versed in this area to help you correct this mistake.
