JNE we are talking about US politics. The reasons Japan and Korea secure their borders aren't relevant to the topic at hand.
But I'll play for just a sec: Japan is a (Franking) island, so um, ya, its neighbors are fish and other sea life. They eat a crap ton of their neighbors. IF I follow your analogy, then you are advocating that the USA should start commercially harvesting Mexicans and Canadians as our primary food source?
Korea is a peninsula...so their neighbors are fish and the totalitarian state to the North that talks about nuking them almost weekly. I covered the relevance of fish above, but are you further indicating that Canada is a totalitarian state run by a deranged despot who is intent on destroying the USA with a pre-emptive nuclear strike? I just thought they drank a lot of beer while eating poitín and watching pucks. Silly me.
See, these are not good examples of borders or relevant to the USA.
In the United States the right talks about tougher borders for one single reason: their poll numbers suck among immigrant groups
. Read that sentence again; just read it. They give not a single (Frank) about hiring cheap, illegal labor - they care about gerrymandering election maps and the immigrants keep (Franking) that up. Don't believe any other story because in the USA it's always about the money. Always.
I stand by my statement that Hannity and his cronies are flat out racists. The RNC paid millions for a study to look at how to reach more offices and the results were "find more white people." You have to be white or delusional to believe their bullshit for anything other than the old boy network.
As far as you and the 2nd amendment, your position isn't a shock to me. How could anyone expect internally consistent philosophy from someone who hasn't received the gift of Christ?
