Even though I personally identify mostly with the Constitutional Libertarian label and am not a conservative in the strict sense, I see the biggest threat to the Constitutional Republic of the USA (and it is a Republic, not a Democracy) as the liberal agenda. In my own opinion, social liberalism is just a vector into complete Socialism and eventually outright Communism. There are some smart people that have said as much but I cannot remember the quotes right now.
As the largest threat, both historically and today, I feel the liberal agenda needs to be addressed first. It's like an arrow sticking out of a wheel that is trying to roll. It needs to be removed completely in order for the wheel to move.
I think the GOP (or Grand Old Party) is almost as corrupt and morally bankrupt as the DNC. Not quite, but almost. After we cut the legs off of the liberals, we can go after the conservatives. It is a matter of pragmatism and addressing the biggest threat first.
It is a problem that so many of the liberals identify with the "Democrat" label. The reason is that they have not gotten the truth about the DNC and its history. It is the most bigoted, racist political organization in the history of the USA. All KKK members were originally Democrats. And most socialist/communist/racist organizations in world history began as liberal movements, not conservative. You won't learn any of that in the public school system and that is by design.
Do your own research.
