That's such an interesting statement when I thought we all had "the right" to believe what we want; define principles and ideals as we see fit; without concern or fear of being maligned by others with an opposing position. Kinda like the way I was taught to "mind my own business"
No one said you didn't.
However, once you decide to force those upon others, by using the government to force them to embrace your ways, and financially support them, things change.
Some beliefs are diametrically opposed, and completely incompatible.
Without going too deep into "politics", although this thread will almost certainly get locked, there are certain ideals, beliefs, and principles which are enumerated and enshrined in the Founding Documents. There is a group that opposes those ideals, beliefs, and principles, and fully intends to eliminate them. They are willing to resort to violence in order to do so.
If you do not agree with those ideals, beliefs, and principles upon which the nation is founded, there are literally dozens of nations where they are not the fundamental basis for the nation. People should go where the system they desire exists.
I count myself extremely blessed to have been born here, in this Republic, and I believe strongly in the Founding Documents, as written, in the context of the time period when they were written, in accordance with the other writings of them men who wrote them, signed them, and offered their very lives and treasure to create the Republic. They say exactly what they mean, they mean exactly what they say.
