Soft drinks, Circumcision, and Burka’s: Beware of the slippery slope!

One of the most common legal and philosophical arguments heard in today's classrooms is the refrain "its a slippery slope".
Slippery slope means that if we intact this law what will come next. For example if we ban trans-fat for health reasons what will the health argument be used for next perhaps red meat?!

However the slippery slope has recently exited the classroom and inundated the western hemisphere.
Governor Paterson (D-NY)is pushing a bill to tax soft drinks in New York, after all soft drinks are unhealthy.

And why not? If we already tax cigarettes at 300 percent and banned trans-fat from restaurant chains, why shouldn't the government combine health concerns with revenue interests and tax soft drinks? We the healthy consummer who enjoy the occasional steak should not be suprised if we are asked for ID next time we enter a steak house!

Yet the slippery slopes of New York are relativity innocuous. 4 major countries in Western Europe have recently moved to ban Burkas (Burqa or Burkha). In France, Britain, Italy, and even Holocaust-handicapped Germany public surveys have shown majority support of a total ban on the full body covering worn by Muslim women.

Why? Frances president Sarkozy sumed it up "the burka message of a women's segregation from larger society is antithetical to Western notion of equality and liberty". Some reading this post may ask two questions.
1. Does this indicate Mendel is pro-burka?
2. What wrong with banning the Islamist burka?

First of all I am not a fan of the Burka nor the extremisim it represents.
Second, this is of a real concern to ALL OF US!

In liberal England parents have been sued for circumcising their son! Moreover a Jewish school is being forced to accept children who were defined as Jewish by the government in opposition to the Orthodox Rabbis Halachic (Jewish law) decision.
In both theses cases the government contends that the actions they overturned were antithetical to Western values. Whats next Shabbos on Saturday and crucifixes around the neck?

The fact of the matter is that certain arguments, though having merit create hazards that we only recognize after the fact.
Beware of the slippery slope!
