I did not ignore the "and", I just chose only to respond to the first part of your statement. You stated, very clearly, that we should "beware of those who teach that Christians must be obedient to an evil government imposed over them". I pointed out, in my reply to you, that Christians are commanded to be obedient to any and all government that they live under. The only time we have permission to disobey government is when government asks us to disobey God. In such situations we, like Daniel and the Apostles, must obey God rather than man. However we must also be prepared to face the consequences of such actions (persecution). Other than that, we are to be obedient to government and respectful towards our leaders. Paul, and Peter, taught us that while living under the reign of one of Rome's most brutal Caesars (Nero).
"yet somehow not be loyal enough to their own nation to protect, defend, and secure the government which they designed, empowered, and are accountable for."
Part of the problem here is your wording. Are you targeting Christians who are not in the military? Or are you targeting Christians who don't believe in using political activism to return government to its original form? It's just not clear from your wording. If the meaning is the later, and must assume it is, then we have yet another difference. Neither Jesus, Paul, nor Peter (etc) took up the cause of Rome. They did not use political activism to try to make Rome a more "Christian empire" (whatever that is). As Christians we are not called to "reclaim the culture" or "return America to small government", no matter how noble those things are. Our mission is to live for Christ as individuals and as a church, evangelize the lost and disciple the saved. Our political beliefs must be (a) secondary to each of those things and (b) must be in agreement with each of those things. Therefore our focus needs to be on our Biblical mission and our approach to politics (and to all of life) must be in agreement with our Christian confession. Too many Christians have fallen into sin by disobeying the Word of God on this matter.
Again, I'm not clear on your specific point in the second part of your statement. I'm just responding to what it seems like you are saying.
