Opinions are what separates normal people from arrogant/dangerous people: The latter proclaims their opinions as facts, whilst normal people presents their opinions as *drumroll*: Opinions.
Nothing in general is a good ideato portray as something it’s not, although the impact of misconceptions for most things have little consequence, opinions portrayed as facts however have started wars, killed millions, suppressed whole nations.
It’s not the opinions that are the problem, it’s the misleading presentation of those opinions as “facts” that does damage.
