If you oppose the health care law, you are not insane. However, if you believe any of the following things, you are "insane," in that you are divorced from reality and clinging to demonstrably false ideas:

1. The law creates death panels.

2. The law provides free or subsidized health care to illegal immigrants.

3. The law provides government funding for abortions.

4. The law "nationalizes" the health care system, or the health insurance industry.

5. Obama is a communist (and/or a Moslem, and/or not born in the US).

6. The law is the "nose under the tent" for widespread "socialism."

If you believe any of these things to be true, you are insane, which is to say, you believe in fantasies. These are not "opinions" which aren't quantifiably true or false; they are assertions of facts which are not real.
