As a conservative in favor of limited government, I'm often asked what kind of government intervention I do support. The answer is simple: I'm in support of people doing anything they want in a free and democratic society -- until their actions infringe on my freedom or anyone else's. At that point, the state ought to step in, if only to maintain personal liberty. If the state doesn't intervene in those instances, when minimal intervention would be required to rectify the situation, then the situation could potentially spiral out of control to the point where extreme measures become warranted.
If your kid is pulling items off of store shelves in a tantrum, you're going to give him an acute little whack on the behind to instill a sense of principle, so he doesn't grow up to rob a bank or something and end up in prison, right? The same holds true for correcting societal behavior that infringes on the freedom of others. Significant but relatively moderate measures prevent more drastic ones later.
Take smoking, for example. As a nonsmoker with a severe aversion to tobacco, I don't mind if someone smokes, as long as it isn't imposed on me. But when someone walks down the sidewalk puffing away and, as an unsuspecting pedestrian, I get blasted in the face with the resulting cloud of smoke, that's a violation of my personal choice not to partake in that activity. Smoke anywhere you want -- but do it with a plastic bag tied over your head, please. Then everyone's happy. Smokers lament the law becoming increasingly restrictive as to where they can light up in public, but it's only because enough of them chose to behave in a manner that imposed upon others' freedom not to smoke.
In the last few days alone, Europe witnessed several examples of socialist leniency going too far under the guise of democratic freedom and personal liberty. In each case, the reasonable and moderate measures were ignored to the point where more serious and limiting ones are now necessary.
Effective a few days ago, France's interior minister, Claude Gueant, banned Muslims from praying en masse in the streets in Paris, where more than a thousand worshippers gather in the streets of the 18th arrondissement every Friday. Banning prayer might sound harsh in principle, but when a highly personal activity becomes an obstacle to traffic and unavoidable by others, then banning becomes a necessity. The common-sense approach to maintaining one's religious freedom would have been to hold prayer groups inside people's homes or inside one of the 2,000 existing Parisian mosques or prayer facilities.
