How to Express Different Views with Your Parents: 'Different View' vs. 'Different Views'

Both options are grammatically correct, but they convey slightly different meanings.

'We have taken a different view on the topic' suggests that you and your parents have collectively arrived at a single alternative viewpoint that differs from each other's original perspective.

'We have taken different views on the topic' implies that you and your parents have individually formed distinct viewpoints that are different from each other.

So, the choice between the two depends on whether you want to emphasize a shared alternative viewpoint or highlight the individual differences in your perspectives.
