Not even classical one-sided economic schools like "Keynesian" are as absolute as you pose it here.
Inflation, nor deflation are bad. Too much of any is. The common consensus is that the scales, on average, should lean a little towards inflation. But only a little. And not always.

I think the common consensus is that any deflation is too much. What's contentious is just how much inflation is acceptable and how much is counterproductive to economic growth.

This depends on how broad you define it. We've seen deflation for the past decade now. In the sense that the buying power of your savings on a traditional savings account have shrunk, while official inflation was below zero at points. We've now bounced back to "high" inflation.
None of this is bad, as we can see clearly by how well tech has benefitted from this (cheap loans, beneficial DCF). This is even policy.

This led to a lot of economic problems with zombie businesses that were able to continue to trade only due to cheap loans and continued asset price growth sans proportionate economic growth. Any this was before we saw any significant periods of real deflation.
