Hitting Wives

Hitting wives is unacceptable behavior…

but how about Criticism of husbands…
is that unacceptable behavior…

should there be zero tolerance for both behaviors…

how is hitting comparable to criticism?

So can we have a definition of criticism?
And perhaps then also a way to point out problem causing behavior that would not be classed as criticism.
If there is no need seen for this latter, how are habitual problems dealt with if they are?
