Relativity

There are issues which have evolved over time and positions from 10, 20, 30 years ago are no longer acceptable in today's world.

Its easy though to look back and applying hindsight condemn views from that time.

In some cases that might be justified, but often it isn't.

Many people had quite different views on the appropriateness of certain sexual behavior.

Wrongly certain things were considered sinful and abnormal by many, a view supported by many people's churches.  That view is now widely condemned as ignorant and wrong.  Not everywhere yet and in some parts of the country and some parts of the world views are still problematic.  Still we just celebrated a month dedicated to acceptance of behavior once considered deviant.

Does that mean everyone who once held those views were evil?  More likely they were misinformed and influenced by societal norms.

Certainly their behavior or beliefs should not be celebrated, but neither should they be condemned.

Some behavior would of course always be wrong, like murder or assault, but beliefs are much more relative.
