It's not rhetoric when it's backed by action. I took the oath. I served and I continue to serve to this day. I've sworn no allegiance to any man, piece of land, or any people beyond the human kind. I've sworn to a document that enshrines a set of ideas and ideals. If you want to be an American all you have to do is do the same. Talk is, indeed, cheap.
Once a month, after saying the pledge of allegiance, we recite the preamble.
FOR GOD AND COUNTRY WE ASSOCIATE OURSELVES TOGETHER
FOR THE FOLLOWING PURPOSES:
To uphold and defend the Constitution of the United States of America;
To maintain law and order;
To foster and perpetuate a one hundred percent Americanism;
To preserve the memories and incidents of our associations in all wars;
To inculcate a sense of individual obligation to the community, state and nation;
To combat the autocracy of both the classes and the masses;
To make right the master of might;
To promote peace and goodwill on earth;
To safeguard and transmit to posterity the principles of justice, freedom and democracy;
To consecrate and sanctify our comradeship by our devotion to mutual helpfulness.
Honestly, I smile every time we do this, because it really encapsulates what I believe. You couldn't even understand the lightness of being while under the weight of the full armor. Everything lines up. No lies, no bullshit. I know who I am, what I believe, and there's no malice or conflicts within me. If we did not have such a corrupt government I wouldn't have any cares but the normal bullshit ones.
Now, if you want to talk cultural supremacy, I'm your guy. Because while I know all people are the same, their beliefs, values, and culture are not at all equal. Some are complete shit, while others contain all the elements of success. This is why Asians are now kicking the shit out of white people at our own game. Faith, family, education, and work ethic, are an indomitable combination. You can find the same things among American Jews, or really any successful people. All we have to do is provide the liberty for that to flourish, and everyone wants it. Everyone wants in. If more of those people want in I'm all for letting them in, even if theirs is a different flavor than mine, but same/same. If they come for free shit and to steal that liberty we should show them the bayonet.
