A little off-topic, but this is a pet-peeve of mine. We need to stop assuming that the US is a "center-right" country. I no longer regard that as a "fact".
I hear what you’re saying about assumptions that this is a center-right country.
But, the liberals start from the position that we are a liberal country, and that liberal values, whatever they are, should prevail. And as the liberal ideology promotes big government, we know that liberals will use the full force of government to impose their views on all of us.
