Society has changed greatly since the 80's and earlier, and in particular, the social issues. For example, if you were told in 1985 that "gay marriages" would be a nation-wide (or even worldwide) issue, you most likely would not have believed it. And if you were ask to support that issue in 1985, you most likely would not have gone along with it; even if you supported gay rights in general.
I'm not limiting this issue to gay marriages, but just using it as an example.
Let me give further explanations of the choices you have.
1) I go by moral standards that do not change
This is referring to conservative religious standards from Judaism, Christianity, Islam, etc. that do not change with the passing of time. For example, this group will always be against abortion, homosexuality, and other social type issues regardless of changes in society. Modest dress will always be the rule (especially in Islam). There would normally be no problem accepting morally neutral changes such as changes in technology, increased civil rights for men, women, disability community, visible minorities, the poor, and other morally neutral groups.
2) I go with society's changes, but only to a point
This group will generally go with changes in society but has their limits. For example, this group might support gay marriages, but not support incest marriages. Another example is that this group might support abortion, but not euthanasia of born babies.
3) I change with society no matter how radical it gets
This group will go along with just about any changes in society. For example, this group might support incest marriages. They might support marriages composed of more than 2 people. Some, but not all people who choose this one, might support pedophilia. They might support euthanasia of born babies for genetic defects or other reason. They also might support certain things that are legal for consenting adults today that may be extended and supported to consenting teenagers and even pre-teens such as alcohol, drugs, sex with partners of any age, etc. Don't think it can't happen. Remember my 1985 example. Not everyone who picks number 3 will support pedophilia, but will generally support radical changes that have yet to take place in current society.
