To determine whether it is wrong, we must first discern the purpose for the expression to be made in the first place
Surely a human could use words to manipulate others to do evil, and therefore it would certainly be wrong to make this form of expression, but so to could a human provoke or stimulate people to act with a goodness in their hearts
Opinions are like ass holes: everyone has one (and most stink). But not everyone realizes this with the same depth, which often raises polarity/friction/clashing issues, resulting in either piss contests or incessant, pointless, ping-pong based delivery of said opinions, raising the page count without adding any substance. So, I wonder, is there moral value? Or should there be?
When people participate, each individual will do so for their own reasons. Often enough it's just another flavour of their sense of self, and thus, for whomever that's stuck in egoland and identification/struggle with thought, and either unware of it entirely, or of whatever is the extent, will fall for this conflicting behavior which is in the nature of such entrapment, and fight fiercely at all external attempts to even bring awareness to it, not to mention the inability to not take any discussion as a threat.
To avoid criticism, do nothing, say nothing, be nothing.
