Narrow questions tend to result in people raising the base question and then others feel obligated to respond. See here as to "anchor baby." I fall in the trap here regarding "undue burden" litigation though end with an extended on point discussion. The "life" question is directly discussed here. The true believer and/or aggrieved tone of such "thread jacking" is a norm too as if "no one" covers this ground or something. The issues should be discussed at times and strict germaneness rules on blogs are a loose matter. But, it is a bit tiring.
