Where is the line.

Last weeks Gun Nuts:TNG pod cast was a good one. During the show a question was asked about where do you draw the line on, in this case, gun rights. But the same question could, conceivably, be asked about any of our rights. Where do we draw the line? I made an off-handed comment along the lines the hindsight is 20/20 and it's easy to look back and say, "Yeah, there's the line we shouldn't have crossed."

Let me put it too you that while something may be glaringly obvious after the fact, as you're barrelling up on it, it's not so clear.

Ask the victims of the Nazi regime and holocaust. It started relatively benignly. Lets just make it easier for "the undesirables" to leave. If they don't, well, we can enact some laws to make it easier. Step by step, a statute here, a demonstration there, suddenly, we've got death camps and pogroms.

Below is a time line of Nazi anti-Semitic growth and the infamous Nuremberg Law.

Do you think most of them knew what was happening until it was too late?

But back to the original point. The Constitution guarantee's some of our most basic rights. Where do we draw the line in defense of those rights from those who would take them away in the name of "our own good" or "for the children" or whatever fallacious slogan they've cooked up? There's often been talk of the slippery slope, but how do you identify those first few steps? When everything seems to make sense and nothing seems to have changed.

I only have my opinion. I'd say that we should have put the line at the point the founding fathers placed it and not one step backwards.
