I think diversity and tolerance are great, but there are many who do not really know what they mean or entail.
I see the bigger problem as social media and the internet in general have given voice--typically anonymous, but not always--to the fringe elements that MSM and these fringe elements try to convince everyone represents the belief of society as a whole. These fringe elements then become even more vocal, frequently violent, empowered by the belief society has their back and everyone with a different viewpoint is wrong and it is somehow their place to teach us all a lesson.
Problem is not the concept. Problem is the execution of the concept.
Diversity and tolerance aren't the problem. The problem rests with anybody who seeks to profit from pushing the idea that they don't exist. The more actual tolerance and diversity there is, the harder the charlatans have to attack anybody who would question their scam.
