If you sift through the laundry list of issues, at its heart social conservatism makes the following comparisons between past and present:
1. Families are less stable than they used to be.
2. Communities are more transient.
3. Social mores regarding behavior have deteriorated.
4. There is less deference to previous generations or their values.
5. Community, national, religious institutions have become less relevant.
On the facts, it's tough to argue the truth of those points (easy to measure stats like divorce rate, crime rate, average number of job/career changes, church membership, etc... and compare it to the same statistics from, say, 1945.)
So, here's what I want to open up to the board for debate: setting aside the issues the social conservatives back today (same-sex marriage chief among them), are those five changes positive, negative, or neutral?
